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

Answer

Uniform linear motion is uniform motion along a linear path or a straight line. The direction of motion is fixed. So, it is not accelerated.
For example: A car running with uniform speed of 10km/hr on a straight road.
Uniform circular motion is uniform motion along a circular path. The direction of motion changes continuously. So, it is accelerated.
For example: Motion of earth around the sun.
