Question

This is a graph of position, velocity and acceleration. How to define which one is position, velocity and acceleration?

Answer 1

whats your best guess ?

Answer 2

we use below :
\[\large a = v' = s''\]

Answer 3

acceleration is derivative of velocity

velocity is derivative of position

Answer 4

(ii) , (iii) and (i) are position, velocity and acceleration respectively.

Answer 5

thats a good guess, but it wont work

if ii is the position, then iii has to become 0 at the turning point of ii

Answer 6

but iii is always negative and decreasing, eh ?

Answer 7

so iii cannot be derivative of ii
