Week 5 blog: Due by 10p.m., Sunday, 2/23/2014
We started talking about projectiles in class this week. I would like you to look around you and think of some projectiles you see everyday. I want you to answer the following questions about your projectile:
What makes it a projectile? Is it a horizontally launched projectile or a projectile launched at an angle? What type of range or height does you projectile have? Any other comments or observations you made about your projectile.

A projectile is something that blows up. If it doesn't blow up that means you did something wrong :)
ReplyDeleteIt doesnt necessarily have to blow up
DeleteAww the rock I threw didn't blow up, what'd I do wrong?
Deletethats totally a projectile...
DeleteYea a projectile is just something that is thrown.
DeleteTrolololol
DeleteA projectile is something that has an initial push or force acting on it that makes it go up, the force going forward and the gravity/resistance on the object are what make it's path. A projectile that almost ALL students have seen would be a paper airplane. Once the airplane leaves the student's hand, it's path is that of a reversed parabola. The airplane can be launched both horizontally and at an angle depending on the airplane type and thrower.The paper airplane can reach distances of 1 inch or as much as 232 feet. The height will vary depending on enviornment and other factors.
ReplyDeleteThat's a great example. I never thought about a paper airplane.
DeleteGreat example man. :^)
DeleteA horizontal projectiles around my house would be a bullet that just escaped the chamber i will guess it eould act like a cannonball how it has a starting point and reaches the maximum or the porbala depending on the position of the gun.
ReplyDeleteGuns are shot often at your house, i assume.
DeleteGreat example of a projectile!
DeleteA projectile is something that is launched in the air and only has the force of gravity acting upon it. Like a golf ball when I go golfing. It launches the ball at an angle, and the height will vary depending on how you hit it. I also observed that the golf tends not to go very high when I hit it.
ReplyDeleteAll that gravity, man. -Erick Ramirez
DeleteGolfing sounds fun. :'l
DeleteA projectile is an object that has been launched into the air and the only forces acting on it are gravity from Earth and, if wind is present, drag force. Such as when I play football, after the ball is released from my hand, it becomes a projectile. It is usually thrown at an angle to give it its intended height and distance. It's path usually resembles one of a parabola from when it is released from my arm to when it becomes motionless. -Erick Ramirez
ReplyDeleteI'm guessing the parabola wasn't very wide.
DeleteA projectile is an object launched in the air, after launch only gravity is acting and takes a parabolic path. Everyone has been to or seen a basketball game, when the player is about to release the ball to shoot a free throw it becomes a projectile. The basketball needs to be launched at an angle in order to receive the necessary distance and height. The range and height is dependent on how much force the player gives the ball when the player initially throws the ball in the air to make a free throw.
ReplyDeleteThat is a good example. That is how the basketball will travel in order to get the point.
DeleteYeah I really never thought of it but the basketball would move in a parabolic shape to get there
DeleteA projectile is an object launched into the air. while airborne it only has gravity acting upon it. For example, my 70's Show Frisbee is thrown at a small angle to reach whomever i am throwing it to. depending on the force applied it'll go a variety of distances varying from 1 meter to 15 meters, or more if thrown hard enough.
ReplyDeleteA projectile is an object launched in the air that makes a parabola shaped path as it goes through the air, and the only force acting on it is gravity. My dad and brother play football, or well just throw the football back and forth at each other and the football they throw is a projectile. It is thrown at an angle, and its height depends on how much force is applied as my brother or dad throw it.
ReplyDeleteYes this is true, it does depend at what angle the football is being launched. This is similar to my example, throwing a baseball.
Deletethis is a very nice example, I felt smarter as I read
DeleteA projectile is anything that can be launched in the air. It can be both horizontally launched and be launched at an angle because horizontal is technically an angle. It can also have any height or range depending on it's mass and the applied force that it was launched with. Think of it like Angry Birds, the guns in Battlefield 4, or Batman's batarangs in Injustice.
ReplyDeletea plan would be most effective rather than a helicopter or a hot air ballon
DeleteNice examples

ReplyDeleteA projectile is an object launched, thrown, or shot. It travels through the air, vertically or horizontally. As it travels through the air, gravity obviously pulls it down, and as well drag. An example of a projectile is when a hitman utilizes a ballistic knife to project a knife at any angle or horizontally to cause harm to the individual who is targeted. This projectile would travel about 15 to 20 feet due to restrictions, partly because there is a set amount of force applied by the device itself and not ourselves manipulating the force applied.
ReplyDeleteGreat example but that's something you never get to see everyday!
DeleteWould using a ballistic knife increase the chances of hitting its target ? Extreme example tho helps memorize projectiles!
DeleteA projectile is something that has an initial push/force and after it's only gravity acting upon it. Like when I throw my brother the ball it goes up and horizontally at the same time and then comes down. The height and force depends on how I throw it
ReplyDeletethis is a projectile.
DeleteA projectile is in a shape of a parabola... In math they teach you that a parabola is a type of graph given to you from specific coordinates... I hope with what i have put here today, you guys would accomplish many goals in life .. Ms.Schramm was here ;D lolololol OTC, TBH, LIKE THIS, DOUBLE TAP!!!
ReplyDeleteA projectile is an object upon which the only force acting is gravity. A great example would be throwing a baseball because the ball is thrown up at an angle and come down, gravity acts on it that's what makes it a projectile. My projectile can reach a high height, it just depends at what angle the ball is thrown. but if the ball isn't thrown high enough than it wont work, I estimate that it should be thrown at a minimum of 45 degrees.
ReplyDeleteA ball does not have to be thrown high to be a projectile. It can have only a y direction.
DeleteA projectile is when object is thrown and the main force acting pn the object is gravity. It also makes a parabola shape. An example of a projectile is when a sofball player throw a ball.
ReplyDeleteA projectile is an object launched in the air that makes a parabola shape and the force of gravity is the only force acting on it. An example that I see a lot in everyday life is when I throw my mom her keys each morning. This is a projectile because when the keys are thrown they make a parabola shaped path from starting in my hands to my moms. The projectile is shot from an angle. The type of height my projectile has depends on the amount of force I put on the toss but I would need to give it quite a bit in order for it to make the parabola shape.
ReplyDeleteA projectile is create by applying force on an object and the other force acting on it is gravity. one of the examples I can think of is when I throw my phone at my bed because I apply force on it to throw it and it makes a parabola shape as it goes towards the direction I threw it and it changed direction when it looses force. a projectile has its own horizontal and vertical equations.
ReplyDeleteA projectile is an object with only a gravitational force acting on it. It can be thrown or dropped. An example of a projectile could be a dart being thrown while playing darts.
ReplyDeleteBut in darts dont you just throw it straight? it doesnt have the parabola shape.
DeleteYour example is of a horizontal projectile.
DeleteWell yes, it would go straight, but it depends on how far away she was from the dart thingie. So I'd consider it a horizontal projectile as well.
DeleteA projectile is an object that is thrown into the air by exertion of force. An example would be an arrow thrown with a bow. It is being thrown horizontally. Just like in the movie Hunger Games, Katniss, will throw the arrow either horizontally, or at an angle. She applies great force in the bow's string giving the arrow a good amount of force. When she puts that good amount of force the arrow will go straight to the object she is aiming at with great force and velocity.
ReplyDeleteI love the movie Hunger Games and I would've never thought of an arrow and bow as an example of projectile.
DeleteA projectile is an object that is in the air moving in a parabola shape and has the gravity forece vector change as it keeps moving (first positive, then negitive) while the speed vector stays the same.
ReplyDeletea projectile is any object that has the force of gravity acting on it. it is launched at an angle like a person kicking a soccer ball. the range and height depend on the forcec and it has a parabola shape.
ReplyDeleteA football is a projectile when thrown. That's because after it is thrown at an angle, gravity is forcing it to come down. And is the only force acting on it in the air
ReplyDeleteThat is a perfect example of a projectile
DeleteWhen playing volleyball, the volleyball creates a projectile when thrown over the net. There is 3 different types of projectiles depending on the angle that an object is thrown. This creates a parabolic shape called trajectory and depending on the force acted on the object the height is affected.
ReplyDeleteThat's a great example of projectile because when the ball is hit it form a parabola.
DeleteProjectile is an object that is launched in the air that makes a parabola and has gravity acting on it. An example is whenever a baseball player throws the ball and the batter misses it, gravity is going to bring the ball down and the catcher is going to get the ball.
ReplyDeleteI've been paintballing before and the ball shoots horizontally then eventually goes down due to gravity. A projectile has the force of gravity acting down which is why it has that curving motion.
ReplyDeleteWouldn't of thought of a paintball that's been shot would be a projectile. I wonder if an object that is going straight up/down is a projectile though. Even I said that it has to curve but I think in class we learned that it didn't need to curve in order for it to be a projectile.
DeleteA projectile is an object thrown and makes a path that you can calculate and solve for using simple physics equations. A baby thrown off a cliff shows an example of a projectile and there are 3 different types of projectiles, vertical, horizontal and at an angle.
ReplyDeleteThat is a very unique example.
DeleteThis is the best example I've read XD
DeleteA projectile is an object launched into the air and after launch, only gravity is acting on it, and it has a shape of a parabola. An example would be while I was watching Law and Order, Detective Benson tazored a criminal, as it was shot out horizontally, gravity pulled it down and it ended up landing on his stomach.
ReplyDeleteThat's a great example and it must have hurt when it reached its target.
Deletewow interesting example
DeleteA projectile is any object in the air that only has the force of gravity acting upon it and was launched into the air by an outside force. An example would be when I throw a ball straight into the air. It has a vertical displacement, a height only reaching as high as I throw it. It would also accelerate at a faster rate when it comes down than when it goes up.
ReplyDeleteAn example would be a football being thrown in the air, causing a parabola, the height would depend on how someone throws it and at the maximum of the parabola it would be zeros, also as the ball goes down, gravity would cause it to accelerate.
ReplyDeleteA projectile is something that is throw into the air and the only force acting on it is gravity. An example of this would be a ball thrown straight up into the air and as it comes down it makes a parabola shape.
ReplyDeleteProjectile is something thrown. It can be horizontally launched or launched at an angle. The range of an angled launch projectile depends on the launch speed and the launch angle ( angel between the launch direction and the horizontal. Examples of some projectile motions are sports like tennis, basketball, baseball, volleyball, golf, football, soccer, diving, ect.
ReplyDeleteA projectile is an object that is airborne, whether it is launched or dropped, and has only the force of gravity acting on it. A good example of this is when a basketball player shoots the ball, once the ball leaves their hand, only gravity acts on it
ReplyDeleteA volleyball thrown in the air is a projectile because the only force acting on it when its in the air is gravity. the height/range depend on how hard you hit the ball and the positioning of it as well. most of the time though the ball will form a parabola when it is in the air and that's my example of a projectile.
ReplyDeleteMost sports do have a projectile acting on them. which also depends on how hard you throw the ball
DeleteFollowing the path of a parabola until reaching its maximum point then gravity squashes it down splashing once aging into the depths of the ocean.Dolphins practice projectiles launching into the air at an angle. The height depends on how much force they used to propel themselves into the air.
ReplyDeleteProjectiles are objects that receive an initial velocity. There are three types. 2 travel along the X or Y axis and are called Horizontal or Vertical Projectiles. The other is Angle Projectile which receives an initial velocity at an angle. An example of Vertical Projectiles would be throwing sit balls at your physics teacher.
ReplyDelete1 v 1 me and lets see who has true mastery over projectile ballistic knives
ReplyDeletea projectile is something being thrown or dropped. It'll make a parabola and only gravity will act on it. an example of a projectile is when i threw a football at my brother. It was launched at an angle
ReplyDeleteA projectile is an object upon which the only force acting is gravity. Right now I'm watching the rockets play and when they are making or at least trying to make a shot, they throw the ball and gravity pulls it down.. which then has us wondering whether they will make the shot. By the way they have lost and so they should of calculated their shots so they can perfectly make them in.
ReplyDeleteA projectile has an initial force pushing it up and then gravity will bring it back down... An example the other day was when Nathan was entertained by oranges so I started throwing one up and it would come back down
ReplyDeleteHah Nathan is adorable and that's a great example of a projectile
DeleteA projectile is an object launched into the air in which the only force acting upon it is gravity. My baby nephew really likes to throw a baby doll around the house he usually throws at an angle. While in the air the doll comes down in the shape of a parabola.
ReplyDeleteThe projectiles we have been learning is when an object is thrown in the air and the only force acting on it would be gravity. An example would be my mom throwing me a sandal or heel when I piss Her off lol and the object is thrown at angle to hit me. Once it misses the shoe will come back down to earth due to gravity.
ReplyDeleteYou should try to measure the angle and the seconds it takes for it to hit you lol.
DeleteA projectile is something that is thrown, catapulted, cannoned, dropped, etc, and the only force on it is none other than gravity. An example of a projectile would be when someone throws their refridgerator at their friendly neighborhood person causing irritation. The refridgerator is the projectile, most likely being thrown at an angle.
ReplyDeleteI was gonna reply to everyone's comments just for the lulz...but I got lazy.
DeleteA projectile is a certain object that is launches either at an angle or any other trajectory . It can happen due to any force such as batting , dropping , kicking ect. This is a free falling object and the forces in the vertical y-component is thr gravitational force. The horizontal varies if there is another object in the way of not of the projectiles path.An example could be when you hit a tennis ball with a racket. Its angle can be all the way to 90 degrees . The wrist is the only joint in the whole human body that can flex/ bend at that angle and it could do so in an outstanding second .
