Q. The incorrect statement(s) from the following is/are
I. A body having zero velocity will not necessarily have zero acceleration.
II. A body having zero velocity will necessarily have zero acceleration.
III. A body having uniform speed can have only uniform acceleration.
IV. A body having non-uniform velocity will have zero acceleration.

Motion in a Straight Line

Solution:

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