## what is velocity

Question 1;- Define the term velocity. What is its S.I unit ? Is it a scalar or vector quantity ?

Velocity : – It is a physical quantity that gives both the speed and direction of motion of the body.

Velocity of a body is defined as the displacement produced per unit time. It is also defined as the speed of a body in a given direction.
Velocity = Displacement/Time

If s is the distance travelled by a body in a given direction and (t) is the time taken to travel that distance, then the velocity (v) is given by
v=s/t

The S.I unit of velocity is ms-1. Velocity is a vector quantity because its description requires both magnitude and direction.
