Question

Q11. What is uniform circular motion? Give some examples of uniform circular motion.

Answer 1

Uniform Circular Motion

When a body moves in a circular path with uniform speed or constant speed, its motion is known as Uniform Circular motion. It is possible for a body to move in a circular path with uniform speed as long as it is travelling equal distances in equal intervals of time. But the velocity of the body moving in a circle with uniform speed is not uniform because the direction of motion is constantly changing.

EXAMPLES:-

1} revolution of earth

2} the movement of blades of fan

3} movement of a hand of clock

Answer 2

$\huge\textbf{Answer}$

Uniform Circular Motion :-

When an object is moving on a circular path with a constant speed then the motion of the object is said to be uniform circular motion.

Example :-

An electron moving perpendicular to a uniform magnetic field.

Revolving of earth

Revolving of stone which is tied with stone.
