Last week we started a unit on uniform acceleration (the car rolling down the ramp). We are still graphing position vs. time(p-t) and velocity vs. time (v-t). I want you to compare and contrast the p-t and v-t graphs from the constant velocity unit (buggy lab) with p-t and v-t graphs from the uniform acceleration unit (car rolling down ramp). Discuss the differences and explain why you think the graphs look differently (specifically, what is going on with the object's motion to cause the change in the graphs.)

The diffrence between the p-t and v-t graph in the buggy lab and the car rolling down the ramp is that the graph lines of the of the ramp ones had a curve to it. While the buggy ones were straight.
ReplyDeleteSo what does that mean about the velocity?
DeleteExplain yourself more. What exactly did those lines represent? What is the purpose of the position vs.time and the velocity vs.time graphs? What motions were occurring?
DeleteI think this is pretty accurate
DeleteI also agree with you Juanita.
DeleteThis cleared up any questions u had.
DeleteWith constant velocity both p-t and v-t graphs have a straight line stating that the motion of the object is going the same rate or at a constant motion while the acceleration p-t and v-t graphs resemble a exponential graph because the object is now going at a different rate because it is accelerating causing the velocity to increase rather than stay the same
ReplyDeletetotally! i understand this
DeleteI like the way you explained the graphs you make it sound really easy.
DeleteWith the acceleration graph there's a greater incline if the velocity is increasing at a constant rate. Also the lines are rather curved than straight because the velocity is changing once the car was gaining speed. The buggy lab was just determining how far the buggy traveled which basically it had a constant velocity the whole time depending on how fast your buggy was going. The lines were rather straight than curved because since the velocity was constant it did not go faster nor slower.
ReplyDeleteNice explanation
DeleteThis was a very simple, straight to the point explanation of the differences between the two labs and the graphs involved, nice job!
DeleteGreat explanation , it makes a lot of sense .
DeleteIn the buggie lab the velocity was constant so in the graph it had a straight line. In the ramp lab the velocity changed as it accelerated causing it to have a curve line.
ReplyDeleteNice explanation it's straight to the point.
DeleteI agree with kassandra, its short but its accurate and East to comprehend
DeleteI liked this explanation it was simple and to the point :D
DeleteIn the buggy lab the position vs time graph was at a constant incline. Therefore, the velocity vs time graph was a straight line horizontally. In the inclined ramp lab and the car the position vs time graph was inconsistent meaning that the car was picking up speed as it went downhill. The velocity vs time graph was therefore inclined diagonally to the positive side.
ReplyDeleteI agree with your explanation.
DeleteYour explanation is very easy to follow, thanks.
DeleteNicely explained
DeleteThank you for this explanation!
Deletei understand this, good explanation
Deletevelocity vs time graphs have straight lines and in position vs time graph the line can be curved or straight. one measure the distance and the other measures acceleration.
ReplyDeletethe difference between the p-t graph on the unit we are currently on is that the graph is always going to be straight but with a little curve in it depending on the speed and for the buggy lab the p-t graph can vary depending on the starting point of the car because it had a constant velocity. As for the v-t graphs, in the unit we are on, the graphs change because there is not a constant velocity and in the buggy lab there was.
ReplyDeleteDuring the buggy lab the P vs. T graph was a diagonal line meaning the car moved at a constant velocity and it was on the ground without any plane. During the car lab the P vs. T graph was a curved line meaning the car had different velocities because of the ramp causing it to gain speed.
ReplyDeleteThe velocity vs time graph looks vertical on the downward ramp lab because it gains speed instead of constantly moving.
ReplyDeleteThat is true. When you go downhill, your velocity is different than when you are moving on a flat surface.
DeleteThe buggy lab demonstrated a straight horizontal line for P vs T because the buggy was moving at a constant velocity towards one direction. In the trial with the car and the ramp, the V vs. T graph, the line was curved because of the inconsistency of the speed the car was going at, the speed was different according to where the car traveled by, since it was an unstable situation(ramp).
ReplyDeleteEasy to understand and comprehend would you change anything about the ramp and car experiment?
DeleteThe buggy lab remained constant the whole time since its speed never increased or decreased .In conclusion that is precisly why the velocity versus time graph is a straight horizontal line while the graph from the trail of the ramp and the car the velocity and speed frequently increse because of the incline of the ramp .
ReplyDeleteyes, quite. Great Explanation Jennifer.
DeleteThe buggy lab consisted of a programmed object designed to move at a constant speed, which caused the p-t of it to be at a positive slope, while the p-t graph of the car down the ramp car wasn't at a constant speed, which caused curves on the graph. In the v-t graphs, the buggy lab was just a straight line across to wherever the constant velocity was, while the car down the ramp lab proved to gain speed so that velocity changed at several intervals which caused the v-t graph to be slanted positive.
ReplyDeleteThis was very well explained.
DeleteIn the buggy lab the velocity stayed consistent which formed a positive slope on the p-t and a straight horizontal line on the v-t graph, but the car rolling down the ramp had an inconsistent velocity because it was gradually speeding up which made curves on the p-t graph and lines being placed on different positions on the v-t graph.
ReplyDeleteI like your explanation
DeleteIn the buggy lab, it was positive because its velocity was the same throughout. It went up on the p-t graph, and was a straight line above the origin on the v-t graph. In the other lab, the car rolled down the board, so it started at a slower pace, so on the p-t it went up slower. On the v-t graph there were lines in several places to indicate a difference in speed.
ReplyDeleteIn a position vs. time graph the slope represents velocity while In a velocity vs time graph the slope actually represents acceleration.Also in the velocity vs time graph the area under the curve represents the displacement of the object..
ReplyDeletegood explanation liz
DeleteIn the buggy lab, the buggies were powered mechanically causing the buggy to move at a constant speed and velocity. In the position versus time graph, the buggy would move at a positive slope from the origin. In the velocity versus time graph, there was a straight horizontal line above the origin throughout the whole process. In the uniform accelerating unit, the car traveled by ramp causing the car to move at an unsteady speed and velocity. In the position versus time graph, the slope was steeper due the increasing speed. In the velocity versus time graph there was many lines above the origin due to the velocity of the car.
ReplyDeleteI compliment your response. Very well explained. I too had the same results.
Deletein a position vs time graph the line of the buggy will curve up if on a slope (going downhill) because its going faster as it travels. if it were on a flat plane the buggy's line would look line a x=y type of graph because it maintains a steady pace.
ReplyDeleteon velocity vs time if the buggy's on the slope it will continue to gain velocity so the line on the graph will continue to rise. if on the flat plane the graph will just have one line.
For the most part the buggy lab was consistent , forming a postive slope, on the p-t graph while the v-t graph formed a consistent line . The car & ramp lab was not as consistent as the buggy lab the speed increased making a curve on the p-t graph & the v-t graph had a positive slope. The reson the buggy lab was more consistent then the car & ramp lab is because of the ramp that made the car move at diffrent speeds while the buggy was on a flat surface. Plus the buggy was running on batteries with a constant speed ,but the car may have changed speed depending if the ramp height on the ramp.

DeleteThe difference is that p-t is changing and each second it moves faster because of the steep ramp. V-t is a graphing the velocity which is always the same regardless.
ReplyDeleteokay so position vs time is like moving faster as the buggie car goes down the ramp making each second slightly longer because of the slope or steepness of the ramp and Velocity vs time doesn't really seem to change as much it basically stays the same through out the whole event
ReplyDeleteIn the buggy lab the p-t & v-t graphs consisted of a straight line due to the cars constant velocity on a flat surface. The p-t graph of the car rolling down the ramp consists of a curved line due to the car's velocity as it rolled down the ramp. The v-t graph on the car rolling down the ramp consisted of a straight line sbowing the car's acceleration of the car.
ReplyDeleteWell said Flor.
DeleteIn the buggy lab the p-t and v-t graphs have a straight line because the object is moving at a constant velocity. The object can change direction or increase its average speed but will always move the same distance in the same amount of time.
ReplyDeleteIn the car rolling down the ramp lab the v-t and p-t graphs, the line is curved because as the object moves it accelerates. The object begins to cover more distance in the same amount of time. It does not move at a constant rate but changes as it slowly increases speed.
This was very well explained straight to the point.
DeleteI agree that this was very easy to understand.
DeleteIn the buggy lab the p-t and v-t graphs were moving at a constant velocity therefore having a straight line. meanwhile in the car rolling down a ramp, the v-t and p-t graphs the line was curved because it wouldn't have a constant velocity.
ReplyDeleteI agree with you completely, my graphs looked very similar to yours.
DeleteWith constant velocity, the p-t and v-t graphs have straight lines which means that the position and the velocity are directly proportional to the time. With the uniform acceleration, the p-t graph has a parabola shape because it is constantly increasing velocity and the v-t graph has the same shape.
ReplyDeleteYes I agree, These two different labs accelerate differently because of the way they were placed, giving them different P vs. T and V vs. T.
DeleteV-t rrepresents difference in speed from start to end
ReplyDeleteP-t graphs the line amd the buggie would not have a steady velocity
The difference is that in the Buggy Lab the car ran in a straight line at the same pace, making our P vs. T graph a constant incline. The V vs. T graph was a straight horizontal graph. Now when the car rolled down the ramp the P vs. T graph was inconsistent , the car got faster as it went down the board. making our V vs. T graph diagonal, increasing up.
ReplyDeleteIn the constant velocity buggie lab you had a consistent velocity which thereafter resulted in the increasing of distance in the p-t graph, and on the v-t graph you had a straight line representing a constant velocity.
ReplyDeleteWhen we applied a platform to the lab, this resulted in the manipulation of the velocity and thus resulted in acceleration. In the p-t graph you had a inconsistent slope due to the increasing velocity, which means more distance traveled per second. In the v-t graph we saw an increasing trend with velocity. We saw the different velocities the car traveled with the completion of the graph, almost as if they were staggered.
We can basically infer that when you roll the car down the ramp its velocity wont ever be constant but always increasing resulting in acceleration
DeleteGood explanation ;)
In the acceleration buggy lab p-t graph the line seams to curve up as time goes because of the ramp. in The acceleration v-t the lines goes up diagonally instead of just going straight.
ReplyDeleteIn the buggy lab the p-t the slope was at constant rate in with which it made the v-t easy to graph because p-t was constant. In the uniform acceleration unit p-t wasn't at a constant rate because at first it was slow and its increased speed drastically towards the end which made the graph curve. And with v-t it will look slanted but not entirely straight.
ReplyDeleteIn the buggy lab the p-t just showed its position after each second while the v-t didn't show a constant velocity because as the buggy went down the ramp it was increasing in acceleration thus making the graph a curve
ReplyDeleteVery good observation.
DeleteI believe the reason why there was a difference is one had a change in acceleration, which made the graph curve. While the other kept a constant velocity.
ReplyDeleteGood explaination
DeleteIn the buggy lab, the p-t and v-t graphs had straight lines because it relied on its own speed and of course was consistent. In the uniform acceleration lab, the p-t graph wasnt at a constant speed becausenit was going faster as it was going ddown the ramp. The velocity on the acceleration lab slighty increases with every second.
ReplyDeletein position vs time graph the line can be curved or straight velocity vs time graphs have straight lines
ReplyDeleteWith the buggy lab the p-t graph will have a constant line and the v-t graph will be a horizontal line above 0. In the car lab the p-t graph will have a curved line because of its acceleration over a couple seconds and the v-t the line will go up for every second .
ReplyDeleteThe p-t on the buggie lab the line will have a constant slope because the car was moving at a constant speed, the v-t graph will have a horizontal straight line bc of the constant slope. in the ramp lab, the p-t graph will have a curved line because the slope is incrasing as time passes by. in the v-t graph the line will be slanted because yhe vel was increasing
ReplyDeleteIn the ramp lab we did the p-t graph had a curved libe due to slope that was increasing . the w-p graph was slightly slanted bc the velocity was increasing .In the buggie lab ,the V-t graph has a straight horizontal line because of the constant slope , which means constant speed.
ReplyDeletein the buggy lab the velocity time graph had a constant slope, just like the p-t graph so they both had straight lines. In the uniform acceleration lab the p-t..graph the car went faster as it went down the ramp causing it not to have a constant speed. This made the graph have a curved line
ReplyDeleteThe graphs are different because of the different positions of the cars. The buggy lad's p-t and v-t graphs motion were constant throughout the process. The uniform acceleration's lab speed wasn't as constant as the buggy's lab speed due to the car picking up more speed as it went down the ramp by the second.
ReplyDeletePretty understandable explanation!
DeleteIn the buggy lab, the speed was consistent, so the line in the graph was straight. The ramp lab's speed was nut consistent; instead, the acceleration cause the cat to go faster, causing the line for that graph to be curvy.
ReplyDeleteThe graphs were different because of the different position of the cars and incline of the ramp, going down the ramp would make it pick up speed while going up would make it lose speed.
ReplyDeletein the buggy lab the buggy moved at a constant speed, the line in p-t graph was a positive slope and in the v-t graph the line was above the origin. in the ramp lab, the car did not move at a constant speed, it gained speed as it went down the ramp.in the p-t graph for this lab the line curved up and in the v-t graph the line was above the origin and it showed the car's speed increasing
ReplyDeletein the buggy lab the two graphs were different. The p-t graph had a constant slope which made it increase and the v-t had a horizontal line representing a constant velocity. Both of the graphs were different due to the position of the cars.
ReplyDeletethe difference between a p-t and v-t is that, the position vs. time graph shows where the object was at a specific time in seconds. as to where the v-t shows how fast the object was moving.
ReplyDeletethe difference between p-t and v-t is that p-t show the displacement of the object by each unit per time, it shows how far the object is from the starting point (or origin depending on the situation) or how close the object is. while v-t shows the constant or not so constant movement of the object by displacement/time.
ReplyDeleteThat's exactly what I was thinking
DeleteIn the buggy lab the p-t graph moved away from the origin at a constant slop and in the v-t graph is constant. In the uniform acc lab the p-t graph has a curve that curves up because it is accelerating. In the v-t graph it has a postitive slop because it is accelerating
ReplyDeleteThat's what I was thinking to
DeleteIn the lab.. in the v-t graph the velocity stayed constant and in the p-t graph it moved away from the orgin at a constant slope
ReplyDeleteIn the Buggy lab the velocity was constant which made the p-t graph have a constant slope moving away from the origin. In the Ramp lab the velocity was accelerating which made the p-t graph curve.
ReplyDeleteThe graphs were so confusing to me but I found little tricks that he'll me rememeber how to graph them and such
