An object is moving along a straight line. The graph shows the object's velocity as a function of time.

-During which interval(s) of the graph does the speed of the object increase by equal amounts in equal times?
A)0 s to 2 s 
B)2 s to 3 s 
C)3 s to 5 s 
D)0 s to 2 s and 3 s to 5 s 
E)0 s to 2 s, 3 to 5 s, and 5 to 6 s

Quizplus · Accepted Answer

The speed of the object increases by equal amounts in equal times during intervals where the graph shows a constant slope, indicating constant acceleration. This occurs from 0 s to 2 s and 3 s to 5 s.
