Question

What is velocity? define it​

Answer 1

Velocity is a measure of how fast something moves in a particular direction. In other words, a velocity is a speed with a direction. For instance, if an object moves east at 9 metres per second (9m/s), we would say that its velocity is 9 m/s to the east.

Answer 2

VELOCITY

“The distance covered by a body in a unit time in a particular direction is called velocity.”

OR

“The rate of change of displacement is called speed.”

OR

“Speed in a definite direction is called velocity.”

FORMULA

Velocity = Displacement/Time

or V = S/t

UNIT

The S.I unit of Velocity in M.K.S system is Meter/second.

or m/s

Kinds Of Velocity

1. Uniform Velocity

If a body covers an equal distance in equal interval of time in a Constant direction so the body is said to be in uniform Velocity.

Variable Velocity

If a body does not cover an equal distance in equal interval of time in a particular direction so the body is said to be in variable velocity.
