Question

Define uniform circular motion. OR Explain the term uniform circular motion.

Answer 1

QUESTION:-

Define uniform circular motion.

OR

Explain the term uniform circular motion.

ANSWER:-

i. The motion of a body along the circumference of a circle with constant speed is called uniform circular motion.

ii. In U.C.M, direction of velocity is along the tangent drawn to the position of particle on circumference of the circle.

iii. Hence, direction of velocity goes on changing continuously, however the magnitude of velocity is constant.

Therefore, magnitude of angular velocity is constant.

iv. Examples of U.C.M:

a. Motion of the earth around the sun.

b. Motion of the moon around the earth.

c. Revolution of electron around the nucleus of atom.

Answer 2

Answer:-

Uniform Circular Motion :

Motion of body along circular path with constant speed ( velocity ) is called as the Uniform Circular Motion.

so we know that direction of velocity changes continuously due to circular path.

some examples of UCM.

1. Motion of planets around sun.

2. Motion of electrons around its nucleus.
