Question

When can the instantaneous velocity of an object be equal to the average velocity of an object?

• A. It can never equal the average velocity
• B. It can only equal the average velocity during acceleration
• C. It can only equal the average velocity when the velocity is constant
• D. It is always equal at the end of a displacement
• E. They are equal at the end of a displacement

Answer 1

Answer: (C)

It can only equal the average velocity when the velocity is constant

Instantaneous velocity can be equal to average velocity when the acceleration is zero or velocity is constant because in this condition all the instantaneous velocities will be equal to each other and also equal to the average velocity. Or distance -time graph will be a straight line whose slope (velocity) is same at every point .
