Question

When a particle is moving in straight line then it's acceleration and velocity

Answer 1

Answer:

This will be abbreviated as m/s2. It is also commonly abbreviated as ms−2. For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, then its constant acceleration is 3 m/s2.

Answer 2

Answer:

The answer will be velocity.
