Question

What is the difference between uniform linear motion and uniform circular motion? Explain with examples.

Answer 1

Uniform Linear Motion:

When a body travels equal distances in equal intervals of time along a straight line, the motion of the body is said to be Uniform linear motion.

The direction of motion is fixed. So, it is not accelerated.

For e.g.: a car running with a uniform speed of 10km/hr on a straight road.

Uniform Circular Motion:

When a body travels equal distances in equal intervals of time along a circular path, then the motion of the body is said to be Uniform circular motion.

The direction of motion changes continuously. So, it is accelerated.

For e.g.: the motion of the earth around the sun.
