Circular Motion and Rotational Motion
Below table highlights the difference between the circular motion and the rotational motion.
Difference Between Circular Motion and Rotational Motion | ||
---|---|---|
Characteristics | Circular Motion | Rotational Motion |
Definition | Motion of object when it moves in circular path | Motion of object when it rotates around an axis |
Defined Path of movement | Circular as the object moves along the circular path | Circular but the object rotates along a fixed axis of rotation |
Axis of Rotation | Outside the body | Inside the body |
Reference Point | Centre of the circular path | Axis of the rotation |
Angular Displacement | Angle through which the object has moved along the circular path | Angle through which the object has rotated along the axis of rotation |
Angular Velocity | Rate of change of angular displacement with respect to time | Rate of change of rotational speed with respect to time |
Angular Acceleration | Rate of change of angular velocity with respect to time | Rate of change of rotational speed with respect to time |
Example | Earth revolving around the Sun in an orbit causing seasonal changes | Earth rotating on its own axis of rotation in the orbit causing day and night |
Circular Motion
Circular Motion is defined as the movement of an object rotating along a circular path. Objects in a circular motion can be performing either uniform or non-uniform circular motion. Motion of a car on a bank road, the motion of a bike well of death, etc. are examples of circular motion.
In this article, we will learn about circular motion and some related concepts, such as examples, equations, applications, etc.
