MCQ
The correct statement from the following is
  • ✓
    A body having zero velocity will not necessarily have zero acceleration
  • B
    A body having zero velocity will necessarily have zero acceleration
  • C
    A body having uniform speed can have only uniform acceleration
  • D
    A body having non-uniform velocity will have zero acceleration
✓

Answer

Correct option: A.
A body having zero velocity will not necessarily have zero acceleration
a
(a)When the body is projected vertically upward then at the highest point its velocity is zero but acceleration is not equal to zero $(g = 9.8m/{s^2})$.
