Question

What does acceleration mean in motions graphs?

Answer 1

Acceleration means the rate of change of velocity, that is, how fast the velocity changes with respect to time.

Explanation:

Acceleration is the gradient or slope of velocity within a certain time interval.
`a=(v_f-v_0)/(t_f-t_0)`
Acceleration can be either positive, or negative (object is slowing down, ie deceleration)
