Which velocity versus time graph or graphs show an object moving with increasing acceleration?

Homework Answers

Answer #1

The average acceleration (a) over a time interval is defined as the change of velocity divided by the time interval

a = (ve - v1)/(to - t1)

where v2 and v1 are the instantaneous velocities or simply velocities at time t2 and t1 . It is the average change of velocity per unit time. The SI unit of acceleration is m s–2 .

Graph of acceleration:

On a plot of velocity versus time, the average acceleration is the slope of the straight line connecting the points corresponding to (v2, t2) and (v1, t1).
