Assertion
A body may have acceleration even when its velocity is zero.
- This statement is true.
- Ex: if we throw a ball from ground, at topmost point its velocity becomes zero but it is still under the effect of gravity , that is, having some acceleration 'g'.
- So, yes object can have acceleration even having zero velocity.
Reason
Acceleration is rate of change of displacement.
- This statement is clearly false.
- As acceleration is defined as rate of change of velocity.
- While rate of change of displacement is velocity.
★ Assertion is true but, Reason is false.
