Question

differentiate between uniform velocity and variable velocity

Answer 1

Uniform Velocity: -
If a body covers equal displacements in equal intervals of time, however small may be, the body is said to have uniform velocity. Its motion is said to be uniform. But be remember that the direction of body all also remain same. If one of them (magnitude or direction) changes then the body will not move with uniform velocity.
Variable Velocity: -
If a body covers unequal displacements in equal intervals of time it is said to be moving with variable velocity. If the body is moving in such a way that the magnitude of its velocity is same but its direction is changing then the body is said to be moving with variable velocity.

Answer 2

hii friend
uniform velocity:
when a body covers equal distance in equal interval of timein a specific direction it is said to have uniform velocity .
for example: a car moving in a straight line with a constant speed of 40km /hr

variable velocity:
when a body covers unequal distance in equal interval of time in a specified direction , it is said to have non-uniform velocity .
a velocity of a body becomes variable if either its magnitude changes or its direction changes
example: all circular motions are examples of variable velocity
hope this helps
