Question
How will you use a speed-time graph to find whether the acceleration of the body is uniform or not?
Advertisements
Solution
A straight line curve on speed time graph indicates that acceleration of the body is uniform and a zigzag or curved line indicates that acceleration of a body is not uniform.
