Question

A body will have uniform acceleration if its

• A. speed changes at uniform rate
• B. velocity changes at uniform rate
• C. speed changes at non-uniform rate
• D. velocity remains constant

Answer 1

The correct option is B velocity changes at uniform rate

If the velocity of an object changes at a uniform rate, then the acceleration that causes the change in velocity is called uniform acceleration or constant acceleration.
For example, the force of gravity imparts an acceleration uniformly which is called acceleration due to gravity.
Hence,option B is correct.
