Question

define the term velocity write the expression​

Answer 1

rate of change of distance per unit time and having its direction is called velocity.

velocity=distance/time

Answer 2

Hey mate!!! Here is your answer ⬇️⬇️

Velocity is the rate of motion of an object, with the direction. It is carried out on displacement of the object. Velocity is the speed of an object moving in a definite direction. If the direction changes, velocity also chenges.

It's mathematical expressions are :-

v=u + at

v is final velocity, u is initial velocity, a is acceleration and t is time.

Other formulae:-

v^2-u^2 = 2as.

s is the distance travelled in a specific velocity.

Its SI unit is m/s or m s^-1

It is a vector quantity.

Hope it helps dear friend ☺️✌️✌️✌️
