Instantaneous acceleration
Question

A particle is moving along a straight line. For this motion you are given two statements A and B. Carefully examine them and select the correct option.

Statement A: The velocity of the particle is always in the direction of its displacement

Statement B: The acceleration of the particle is always in the direction of its velocity

Easy
Solution

Velocity = displacement/time interval suggests that A is true. If the particle is slowing down while in motion, the direction of acceleration is opposite to that of velocity
