उत्तर
| Uniform velocity | Variable velocity |
| If a body travels equal distances in equal intervals of time along a particular direction, then the body is said to be moving with a uniform velocity. | If a body travels unequal distances in a particular direction in equal intervals of time or it moves equal distances in equal intervals of time but its direction of motion does not remain same, then the velocity of the body is said to be variable (or non-uniform). |
| Example - A body, once started on a frictionless surface, moves with uniform velocity. | Example - The motion of a body in circular path, even with uniform speed is with variable velocity as the direction of motion of body continuously changes with time. |
