What is Circular Motion?
An object moving in a circular trajectory around a point is said to be performing a circular motion. For example, a car turning on the road is performing a circular motion around some centre. The circular motion of continued is periodic in nature. Periodic motions are motions that repeat themselves after a certain period of time. Based on the velocity and the acceleration, this motion can be classified into two categories –
- Uniform Circular Motion: When a body moves at constant speed in a circular motion along the circumference of the circular trajectory, it is called Uniform Circular Motion.
- Non-Uniform circular motion: When a body moves in a circular motion along the circumference of a circular trajectory in such a way that its speed keeps changing. It is called a non-uniform circular motion.
Dynamics of Circular Motion
Circular motion is a motion in which an object moves around a fixed point in a circular motion. It can be both uniform and non-uniform. If there is no tangential component of acceleration then it is a uniform circular motion, and if the tangential component of acceleration is present, then it is a non-uniform circular motion.
There are lots of examples around us in our daily lives where bodies perform circular motions every day. From the hands of the clock to a car turning on a banked road. All these are examples of circular motion. This motion can be classified into two categories – uniform circular motion and non-uniform circular motion. It is essential to know the dynamics and the equation of the body performing the circular motion. These dynamics allow us to analyze these motions and calculate the statistics related to the behaviour of the body in such motion.
