Difference Between Periodic Motion And Rotational Motion. In this article, you will come to know about what is periodic motion, what is rotational motion, and what is the main difference between periodic motion and rotational motion.

Both the terms are types of motion. There are various types of motions. A movement of the object is known as ‘Motion’. But there is a difference between them. First, we will discuss the main difference between periodic motion and rotational motion, then discuss the difference in detail.

## What Is The Main Difference Between Periodic Motion And RotationalMotion?

The main difference between periodic motion and rotational motion is that the:

-Periodic motion is a type of motion in which an object moves on the same path with a constant speed at regular intervals of time. For example, a car moving on a race track at a speed of 40km/hr.

-Rotational motion refers to the movement in which an object rotates on its axis. For example, the movement of the earth is on its axis, the rotation of the windmill, or the blades of a fan.

### What Is Periodic Motion?

Periodic motion is a type of motion in which an object moves on the same path with a constant speed at regular intervals of time. The movement of the object is repeated after a certain time period.

For Example, a car moving on a race track at a speed of 40km/hr. The movement of the simple pendulum is periodic. The movement of the clock is also a periodic motion.

### What Is Rotational Motion?

Rotational motion is a motion at a fixed point. It refers to the movement in which an object rotates on its axis. An axis is a fixed point of rotation that is perpendicular to the plane in which the body is rotating.

For example, Earth is rotating on its axis, which is a rotational motion, blades of the fan, rotation of windmill, turning of the wheel, etc.
