Introduction
Giant Wheel, Wheels, Merry Go Round, Top etc. all rotate about a centre. Thus, they are said to be under uniform circular motion as their velocity only changes the direction at every point but has a constant magnitude.
Pre-Requisites:
Motion, Equations of motion
Activity:
Look at a clock, what is the displacement and distance covered but the tip of the small hand in 30 minutes?
Real Life Question:
How do you describe the motion of a wheel?
