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) When the body is projected vertically upward then at the highest point its velocity is zero but acceleration is not equal to zero $\left(g=9.8 \mathrm{~m} / \mathrm{s}^2\right)$.
