Week 4 blog: Due by 10p.m., Sunday, 2/16/2014
We have been talking about forces for several weeks now. Take a look around you, think about what forces you experience everyday. What forces can you identify from your surroundings? What forces are acting on you while sitting, running, jumping, falling, etc.?
Think about a time when you went to an amusement park, carnival, swimming pool, or Splash Town. What forces were acting on you then?
Try to identify forces for an activity/situation that has not already been done by someone else.

When i was a kid my mom would take me to the beach, now i know there was a bouncy force acting on me. Some forces i've experienced today vary vastly, from gravitational forces to those of tension and thrust.There were gravitational forces pulling the bags down and my force applied picking them up but the most memorable one was when i was when i was playing soccer with some pals. Two of them were running towards the ball very fast but one was significantly bigger than the other. Needless to say the smaller one went flying due to the tremendous force applied to him.
ReplyDeleteNice use of your knowledge of physics! I would also go to the beach as a kid btw :)
DeleteThat is a good way to describe net forces.
Deleteik im suppose to understand all of this but I'm still a bit lost i need to go to tutorials.
Delete^ i feel you
DeleteGreat example!
DeleteGood example bro!!
DeleteWhen you're in a car, the engine makes the car go with an applied force. Then when you need to break, a friction force slows you down to a stop. The gravitational and normal force also affect the car.
ReplyDeleteI think the engine would also have a mechanical force.
DeleteI agree, the simplest things may consist of many different forces like this car it takes so much for it to work.
DeleteWhen you walk you experience a gravitational force, a normal force and also friction between your feet and the floor. However, when the floor is wet, there is less friction, and you have more trouble walking.
ReplyDeleteI agree with this comment everyday walking contains many forces
DeleteYes imagine we never thought that such force existed except gravity and all this time we would jump and run never knowing!
Deleteits like when you get hit bye the door on on the way to your class there is an applied force on the person and a frictional force on the person too by the ground.
ReplyDeleteAnd the applied force from your face on the door. Newtons 3rd law
DeleteIn the movie Rio (the cutest movie ever) Rio is a beautiful bird who cannot fly when he tries to he talks about the thrust force the net force.It is a very good example , he got his knowledge from a book of airplanes because he was trying to learn how to fly. In splashtown in the wave pool, the waves exert a force on you and you exert a force on the waves.
ReplyDeleteI love that movie! I remember that part when he tries to fly by reading the airplane books. I never thaught much of it until now.
DeleteI never paid attention to that part of the movie but great reference!
DeleteSo then since Nemo had one fin that was smaller then the other does that mean he had an unbalance force and had to use more force on the smaller fin?
Deletenow the next time I see this movie I'm going to be thinking your example
DeleteOnce I had got on a ride in the rodeo were it went all the way and stopped. Then after a 3 second countdown it would fall really fast. The forces acting on me is a gravitational force and a thrust force.
ReplyDeleteThat sounds like a ride i would never go on lol
DeleteSounds like a fun ride
DeleteA regular force experienced everday is the gravity of the earth but also the normal force that keeps us walking alongwith the force of friction we use in order to stop from bumbing into others all of theses partake in normal life . Last time when i was on the swings the force of gravity kept me from flying into space but also the applied force or thrust from the ground by my foot propelled me to the hight i wanted to go . In the first Harry Potter movie they have to make a feather ignore the normal force by lifting it into the air which then gravity would still have a play in it.
ReplyDeleteYes, everyday we experience the gravitational force and the normal force when we walk or stand still. The swing is a great example Jennifer.
DeleteWe dont realize that we use different forces in our everyday lives. Like today in my 5th period our teacher let us work in groups. He told us to move around the desk if needed to finish the assignment. I used applied force in order to move my desk to its destination. i used an applied force on the object, the force was exerted to the desk by me.
ReplyDeleteEveryday we experiance forces acting on us. For example, when we are standing up on the floor we have a gravitational force pulling us down but we also have a normal force going up because we are on a floor. These forces are equal and opposite forces which explains why we dont move when we are just standing up. Its also the reason why we arent floating all around the place.
ReplyDeleteWhen i was a kid i went to SplashTown and i would get in the wave pool and when the waves were on there was an applied force pushing me backwards and forward and the gravitational force along with the normal force that was holding me down
ReplyDeleteWhen my brother was little he was to scared to get into the pool with out his floaties. The floaties exerted a force on the water and the water exerted the same force on the floaties keeping him from sinking. Also one time I was ridding my bike down a hill very fast when I suddenly (idk why) braked and the front wheel stopped and my body went forward over the bike. An object in motion stays in motion until a force is exerted upon it.
ReplyDeleteIt's so awesome to have floaties for people that don't know how to swim (like me) so we won't drown (: thanks to that force the water exerts we can float with no problem.
DeleteI also experienced flying over my bike but the bike stopped and I kept moving because a rock was in the way and I didn't see it. It was very painful but the flying part was fun.
DeleteWe encounter forces everyday and one of the times were I've experienced it more was when I went to an amusement park and got on a rollercoaster. When we were going up the mountain it was an applied force by the rollercoaster but once we got to the top and went downhill it was gravity pushing us down making us speed up as we went through flips and turns.
ReplyDeleteForces are used everyday and at all times. I remember last summer when i went to schlitternbahn i got on a really huge water slide, when I was on it I felt like I was going to fall but the frictional force made me stay on the slide and gravitational force made me go down with speed.
ReplyDeleteYeah forces are used everyday
DeleteWhen I play football I encounter many types of forces like of course gravitational force and normal force and etc..
ReplyDeleteDo u encounter friction
DeleteWhen I play basketball I encounter the force of gravity when I jump up... also I have a normal force
ReplyDeleteWhen I go roller skating I encounter the gravitational force, normal force, applied force, and frictional force. I push my self against the skating rink floor so I can accelerate therefore using an applied force and the frictional force. Also when I go dance I encounter a gravitational force and a normal force. Forces are used in our everyday life.
ReplyDeleteYeah that is right. I wish I knew how to roller blade that would be fun.
DeleteI am in colorguard so I toss flags all the time.The force applied on me when I toss is the force of gravity that holds me down on the ground. When I toss the flag, I have to push the flag with one hand and lift it with the other. The force of lift and push are applied on the flag and the force of gravity makes it come back down again.
ReplyDeleteForces are everywhere at all times ! One of the forces I can recall is when I was baby sitting my little brother when he was 1 year old, and loved to jump on my bed. there was a hole in between my bed and the wall where he fell into head down and I thought I had to use a tension force to pull him back up. He had a gravitational force by the earth even if he was head down.
ReplyDeleteNewtons laws apply everywhere , newstong law of intertia is applied on a door , and its turned due to the hinges it hangs on. And you can feel the wind as you swing it with rage , like how my little brother Slams the door.
ReplyDeleteI wonder how much force the wall receives from someone slamming a door. Would the normal force between the small area of the door that actually touches the door frame and the door frame be great enough to MOVE a wall?
DeleteWell an every day force acting on me would the gravational force and normal. Whether I am standing of sitting down those forces are scting on me. When I go to Six Flags get on rides that allow me be on a raft and float on water. That force would be bouncy. When I get on the ride boomerrang the ride is held at an angle. The force of friction, normal, and gravity allow the ride to stay there before the ride starts.
ReplyDeleteI was just about to use the ride reference as well, there are so many forces acting upon it. There's also an applied force from the motor to shoot us out or to take us to the top like superman.
DeleteThe forces that are always acting on me are normal and gravitational. Whenever I go swimming buoyant force is acting on me to keep me from sinking to the bottom of the pool. If I were to be at the beach swimming against the waves that would be drag force.
ReplyDeleteYesterday my mom asked me to move a box to her room, there was a gravitational force keeping the box on the ground, a normal force exerting itself from the ground, an applied force by me when I started pushing it, and a frictional force given in the opposite direction of the applied force. Forces apply every where.
ReplyDeletereally good example :)

ReplyDeleteEveryday we experience a force whether we are applying that force or the force is being acted on us. Everyday we experience a traction force from walking, a normal force by the surface we are, gravitational force from Earth, etc. In our everyday routine, whether we notice it or not, there are forces acting on us such as taking out the trash, walking your dog, playing outside, or just sitting down watching TV. As I am typing this text there is a gravitation force, normal force, frictional force, and an applied force acting on me. -Erick Ramirez
ReplyDeleteGreat explanation, and great username dude XD
DeleteWhen my brother was younger, he used to put all his toys inside his wheel barrel and he would push them around. There was a gravitational, normal, frictional, and applied force acting on the wheel barrel.
ReplyDeleteEveryday, I move my wireless mouse inside the confines of the mouse pad. I place an applied force on the mouse in any direction, the mousepad pushes the mouse up while earth pulls it down to form the Normal and Gravitational forces. As I move the mouse, it receives friction from the mouse pad. All of these are on the mouse of course, while I am sitting on my bed. I get a Normal force from the bed and a gravitational force from earth.
ReplyDeleteWait, how does the laser actually touch the mouse pad? I thought the laser read the movements or unless you still have the mouse with the little ball. Well whatever, I'm not a mouse expert.
DeleteI was watching an Olympics' commerical and when the athletes were little kids they were continuously falling, but their mom's picked them back up. So the frictional force made most of them fall, the force of gravity and normal force keep them stationary, but the mothers pulling force helped them back up.
ReplyDeleteWell everyday, we always experience the force of gravity and the normal force. When I was little, I liked to run down hills in Mexico. There was a gravitational force which is why was able to run at a faster speed since it's a incline. There was also a normal force perpendicular to the surface and frictional force on the opposite direction I was going.
ReplyDeleteNice knowledge of your forces man.
DeleteI liked how you used past experience to demonstrate how you used the forces.
DeleteWhen I would push my nephew in the grocery cart there was a gravitational and normal force keeping the cart from floating in the air. There was also an applied and frictional force keeping the cart moving at a constant velocity. When I started pushing harder the frictional force was not equal to the applied force allowing the cart to accelerate which would make my nephew laugh because he would be moving faster.
ReplyDeleteThose are great examples of forces :)
DeleteThe forces that we most experience everyday are the normal and the gravitational forces. When I wake up I walk on a surface and gravity pulls upon me. I'm a dancer so everytime I leap or jump the gravitational force acts upon me and makes my jumps lower:( Also when I turn on my foot I experience the frictional force that prevents me from falling. Whenever the summertime comes and I swim on the pools the buoyant and thrust forces act upon me. It's amazing how many forces we experience daily.
ReplyDeleteWhen I was playing Resident Evil Revelations, the character that I was controlling, Jill, had the force of buoyancy allowing her to float so that she wouldn't drown.
ReplyDeleteAlso, when an Ooze zombie begins to grab Jill with its mouth...pipish rope thing that latches onto her neck to suck her blood, that is a force of tension, for the zombie is pulling her towards it with that. Jill's resistance is a great example of net force, because if you repeatedly press A, Jill's force (opposite of the zombie's tension force) becomes stronger, and the net force will then be in her favor (she pulls the zombie her way and proceeds to attack with a powerful kick).
I forgot to add that the game takes place on a cruise ship, and that in some parts, Jill has to swim through flooded areas, and that's where buoyancy kicks in
DeleteDuring the summer, I would go for a swim at the MacArthur swimming pool. When I dove into the pool I had the force of gravity acting on me as well as a small drag force.
ReplyDeleteWell on my way to these type of areas im usually speeding. So when i slam the gas I feel the force of gravity keeping me down on the ground and the force of thrust pulling my back onto my seat from the rapid acceleration. As im typing this i am sitting down at a computer with the force of gravity keeping me on the chair and not letting me just float into the air.
ReplyDeleteLast time I went to Splash Town I went on that one tall slide. I guess the gravitational, normal, and friction force were present as I slid down. It was super fun.
ReplyDeleteI remember when i was little i would always be in the tug of war on sports day and i had normal, tension,and frictional force acting one me.
ReplyDeleteGreat example Mo-mo. :)
DeleteEvery summer I love to go swimming to different lakes or swimming pools and all that, and the force of buoyancy acts on me so I can float and also acts on the beach balls and floaties my little brother uses.
ReplyDeleteI never thought of the forces acting on he beach balls
DeleteWhen we are waking up in the morning and saying that we would like to stay in bed and not go to school, we are experiencing some forces. The gravitational force keeping us in bed. The normal force countering the gravitational force. Also the thrust force is used when we are getting out of bed.
ReplyDeleteStop being lazy John-_-
DeleteVery good example by the way. This is something we may all relate to.
When I was watching The Walking Dead, there were a lot of intense scenes that made me want to jump out of my seat, but due to gravitational and normal forces being balanced, I managed to not fall and look dumb.
ReplyDeleteI love that show and yes i always fall back on my couch thank good i dont move so much due to the resistance my couch gives.
DeleteI work at a Furniture store and we constantly get new furniture . The other day I was testing the mattress and I saw a significant difference between two. One was a pillow top and the other was a memory foam. When you lay on a mattress you always sing down and i noticed that depending on how many springs it has then thats the force acting up . But the interesting thing is that force varies on how much pressure you put . The memory foam on the other had has no strings and its still firm this was of the force of tension because it just acts on certain point you lay on. its all cushion .
ReplyDeleteI remember my first date. I was so nervous sitting in the theater I was pushing down in my chair just to make sure my date didnt notice that i was shaking so much. While I was pushing into the chair it exert a normal force as well.
ReplyDeleteWhen i was about three years old my uncle would throw me up in the air then catch me. In this scenario several forces are acting on me. First of all, my motion is accelerated because the forces are unbalanced as i am thrown in the air. So to begin there already exists a gravitational force on both me and my uncle, then he applies a force on me upwards. Then as i am projected into the air, air friction acts in the opposite direction. Then after i reach the highest point, i come to a near stop an gravity pulls me down to earth.
ReplyDeletei do that to nathan and believe me the heavier they get the harder it is bc gravity pulls down much more :)
DeleteThe other day i was helping my mom hang up pictures and one portrait didn't have a place to have it from the center so being the mexicans we are she told me to get some string and attach it to the loops there were in the portrait so now the portrait hangs on the wall and gravity is pulling down and tension is holding it up. :)
ReplyDeleteMy mom does the same with the our family portraits lol
DeleteForces are everywhere! I'm probably the clumsiest person ever and so I'm constantly fall. I'm what people call "uncoordinated". But the gravitational, normal and friction forces are acting on me are when I'm running trails. Trails has many hills so I'm constantly having to run up and down. But then when the forces are unbalanced (which they are half the time) I fall. :(
ReplyDeletesame here.
DeleteOne time during my baseball game there was this guy that swung at the ball and made it go high up in the sky... Well the force that brought the ball back down was the force of gravity. The force the batter used to hit the ball was applied force. There are forces found all around us, who would of known... ^-^
ReplyDeleteThat is a great example of a gravitational force.
DeleteI am apart of the dance team so it requires me to dance every morning. While im standing up dancing the gravitational and normal forces are acting on me evenly causing me not to loose my balance. But if I do a leap the frictional force is acting on me as I move across the floor and when I leap the gravitational force brings me back down.
ReplyDeleteWhen I play tennis im applying force to my racket to be able to hit the ball. Gravitational force is always being used. I also have to be able to tell how much force the other person is applying on the racket so I can know where to stand and wait for the ball.
ReplyDeleteWhen someone is bench pressing, the weight on the bar has a gravitational force and the person lifting the bar must overcome that force to force the bar up. The force the person applies on the bar in the force applied.
ReplyDeletewell you also have to apply a certain amount of force when you bench press because the weight with the gravitational force is large. And you don't want those weights to come down on you
DeleteWhenever I skate i push the floor with my feet in order to increase my speed. That would be an example of an applied force. And i tend to have to do that alot because as i ride i also slow down because of the friction on the wheels with the ground.
