Question

Under what condition is average velocity equal to instantaneous velocity?

Answer 1

When the object travels with uniform velocity, then the average velocity is equal to the instantaneous velocity.

Answer 2

Average velocity is equal to inst-antaneous velocity when there is no acceleration.

• When a body is moving with a uniform velocity, we can say that it is not accelerating, or the acceleration of the body is zero.
• During uniform motion, or when a body moves with uniform velocity, all the inst-antaneous velocities at various inst-ants will be equal and will also be equal to the average velocity.
• Distance-time graph for such a motion will represent a straight line.
