Question

if the velocity of a particle is zero can it's acceleration be non zero ? explain​

Answer 1

$\huge\boxed{\underline{\underline{\green{\tt Solution}}}} </p><p></p><p>$

We know that acceleration is rate of change in velocity

$accelaration \: \: = \frac{velocity}{time}$

Since velocity is zero

So the acceleration is zero

Answer 2

Yes. Acceleration is the time rate of change of the velocity of a particle. If the velocity of a particle is nonzero at a given moment, and the particle is not accelerating, the velocity will remain the same; if the particle is accelerating, the velocity will change.
