Question

Create a velocity-time graph from these values: Position: 0, 6, 14, 25, 40, 60 Time: 0, 0.3, 0.6, 0.9, 1.2, 1.5

Answer 1

First you need to calculate the velocities for each time. Take that by dividing the position by the corresponding time. When you have the velocities, line them up with the proper times and wala! you have coordinate pairs :)

Answer 2

Im confused...

Answer 3

6-0/0.3-0, ...

Answer 4

Velocity / time graphs have time on the x axis and velocity on the y axis. The information you have provided does not include velocity.

So you have to calculate them.

Answer 5

Ok, the values for the vt graph are: velocity: 0, 20, 26.67, 36.67, 50, 66.67 and the time is the same

Answer 6

When I calculate the slopes of this, The at graph values are so large

Answer 7

make scale for the graph so that it will adjust.

Answer 8

?

Answer 9

As long as your velocity measurements are correct, you simply graph the coordinate pairs

Answer 10

put one unit on y axis = 20 or 40 or 50 ... so that it would adjust.

Answer 11

Can you calculate the at values, im not sure how to

Answer 12

the at values? what is at?

Answer 13

accelaration-time graph values

Answer 14

yes ... that would be after you calculate vt graph.

Answer 15

Ok, the values for the vt graph are: velocity: 0, 20, 26.67, 36.67, 50, 66.67 and the time is the same

Answer 16

Acceleration is the change in velocity over time. Like experimentX said, you need the velocity values first.

Answer 17

Ok, the values for the vt graph are: velocity: 0, 20, 26.67, 36.67, 50, 66.67 and the time is the same

Answer 18

So acceleration would be the velocity values divided by the corresponding time.

Answer 19

They are so large though, It doesnt seem correct, I got : 66.67, 22.23, 33.33, 13.33, 55.57

Answer 20

hmm... are you using change in velocity over time?

Answer 21

I did v/t

Answer 22

Check your values...the second one, I got like 44, not 22

Answer 23

I did 6.67/.3

Answer 24

26-6.67/.6-.3

Answer 25

**26.67-20/.6-.3

Answer 26

hm...well the velocity should be increasing and the acceleration appears to be increasing as well...

Answer 27

yea...

Answer 28

hm i guess plot the values you got and see what kind of curve it makes
