Distinguish between uniform velocity and variable velocity.

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. |

Sachin and Sameer started on a motorbike from place A, took the turn at B, did a task at C, travelled by the route CD to D and then went on to E. Altogether, they took one hour for this journey.
Find out the actual distance traversed by them and the displacement from A to E. From this, deduce their speed.
What was their velocity from A to E in the direction AE?
Can this velocity be called average velocity?
Define Velocity.
A body goes from P to Q with a uniform speed of u and immediately returns back to P at a uniform speed of v. what is the average velocity for the whole journey?
If the velocity of an object increases with respect to time, then the object is said to be in______ acceleration.
Assertion: The Speedometer of a car or a motor-cycle measures its average speed.
Reason: Average velocity is equal to total displacement divided by total time taken.
