Question

If velocity is zero , then should acceleration be also zero or not? Explain

Answer 1

not in a circular motion
because it changed direction at every point

and if it is in a free fall then at the max hight the velocity will be zero and acelleration will be 10m/s^2

Answer 2

no. if velocity is zero it doesnt mean acceleration is zero.. suppose u throw a stone up in air. at maximum height the stone will stop which means.. it velocity is 0 bt it has acceleration=g by which it get down to earth
