Question

The magnitude of velocity of a body can change even if its acceleration is zero.

• A. True
• B. False

Answer 1

The correct option is B False

Acceleration is defined as the rate of change of velocity.

Acceleration $a=\frac{\Delta v}{\Delta t}$

If the acceleration is zero i.e. $a=0$

$⟹\Delta v=0$

So, magnitude of change in velocity is zero.

Thus the above given statment is false.
