5. Speed may or may not be equal to velocity.

6. Speed never decreases with time. For a moving body, it is never zero.

7. Speed in SI is measured in ms-1

VELOCITY:-

1. It is defined as the rate of change of displacement.

2. It is a vector quantity.

3. It can be negative, zero or positive.

4. Velocity is directed speed.

5. A body may possess different velocities but the same speed.

6. Velocity an decrease with time. For a moving body , it can be zero.
