Choose the incorrect statement:

Moderate

A

In one dimension motion, the velocity and the acceleration of an object are always along the same line
B

In two or three dimensions, the angle between velocity and acceleration vectors may have any value between 0 and 180°
C

The kinematic equations for uniform acceleration can be applied in case of a uniform circular motion
D

the instant acceleration of an object in circular motion is towards the centre only if the speed is constant

Solution

The kinematic equations for uniform acceleration do not apply in case of uniform circular motion because in this case the magnitude of acceleration is constant but its direction is changing.
