Question

What is meant by Circular motion? Give one example.

Answer 1

In the topic ‘Circular motion’ the word Circular means a path that is along a circle and motion means the movement of an object. So, the movement of an object in a path along a circle is the Circular Motion.
It may be uniform, with a constant angular rate of rotation and constant speed, or non-uniform with a dynamical rate of rotation.
Note that, since the object moves along a circular path the distance from the axis of rotation is always the same.

Complete step-by-step solution:
When an object moves along a path that follows a circle, the motion of the object is called circular motion.
There can be two types of circular motion: one is the Uniform Circular motion and another is the non-uniform circular motion.
The object can move with a uniform circular motion with a constant speed and with an unchangeable angular rate of rotation.
And, The object can move with a non-uniform circular motion with a changeable rate of rotation.
Example:
When an Artificial Satellite moves along the orbit of the earth, this movement is called the circular motion of the Artificial Satellite.

Note: Uniform circular motion will be represented as the motion of an object in a circle at a uniform speed. an object moves in a very circle, it's perpetually dynamic in its direction. In any respect, the article is moving tangent to the circle. Since the direction of the rate vector is the same because of the direction of the object's motion, the rate vector is directed tangent to the circle in addition.
In a non-uniform circular motion, the object’s motion is on a circle, however, the object’s speed isn't constant. above all, the subsequents are going to be true
The object’s velocity vector is the tangent to the circle.
The speed and angular speed of the item don't seem to be constant.
The angular acceleration of the item isn't zero.
The acceleration vector won't purpose towards the center of the circle.
