Question

What is uniform cicular motion? Give five examples. Give formula to find velocity when an object moves in a circle of radius r?

Answer 1

Answer:

• The motion of an object in a circle at a constant speed is known as uniform circular motion. As an object moves in a circle, it is constantly changing its direction.

• The rotation of the blades on the ceiling fan
• A stone which is tied to a rope and is being swung in circles
• A car turning through a curve in a race track
• Movement of Ferris Wheel
• Revolution of Earth and other planets.

forlmula to find velocity= 2 π radius/time
