# Difference between Circular Motion Periodic Motion and Rectilinear Motion

Circular Motion is a type of motion in which items move in a circular direction whereas Periodic Motion is a sort of motion in which the item repeats its motion after a certain amount of time whereas Rectilinear Motion is the movement of things along a straight line.

Here are some of the main differences between circular motion, periodic motion, and rectilinear motion to help you understand how both differ:

## Circular Motion Vs Periodic Motion Vs Rectilinear Motion:

### Circular Motion:

The Circular motion can be either symmetrical or asymmetrical.

In a uniform circular motion, the angular rate of rotation and speed is consistent, however, in a non-uniform circular motion, the rate of rotation fluctuates.

When a particle moves along the perimeter of a circular route, it is said to be executing a circular motion.

A key feature of circular motion is that the direction of motion changes continually, as opposed to linear motion.

As a result, the circular motion may also be represented using angular variables. In a uniform circular motion, the instantaneous acceleration is given by a = v2/R.

Examples include clock hands, fan blades, the rotation of the earth around the sun, and so on.

### Periodic Motion:

The mobility of a body is best described as periodic motion.

If an item or body moves in such a way that its place or motion repeats at equal intervals, that element or body’s motion is said to be periodic.

Angular frequency characterizes periodic motion. In this case, the body replaces at an angle at a certain speed known as angular speed.

Angular speed may be calculated as- = 2 f, where is the angular speed and f is the frequencies.

Examples include the pendulum of a clock, the motion of a child on a swing, and so on.

#### Rectilinear Motion:

Since we just require one coordinate axis and time to depict a particle’s motion, we call it linear motion or rectilinear motion.

If an object is moving at a constant speed with no acceleration, this is referred to as uniform rectilinear motion.

Uniformly accelerated rectilinear motion: This happens when an object moves at a consistent speed.

Since an object travel at an unequal speed and acceleration, this is referred to as rectilinear movement with non-uniform acceleration.

Examples include troops marching by, sprinters in a race, falling stones, and so forth.

### What is the Difference between Circular Motion, Periodic Motion, and Rectilinear Motion?

Circular motion is defined as the movement of an item while spinning in a circle while periodic motion is defined as motion that is repeated at equal intervals of time while rectilinear motion can be defined as movement that happens only in one direction.

Now let’s compare and contrast circular motion, periodic motion, and rectilinear motion.

### Conclusion:

This post instructed you a lot about the distinctions between circular motion, periodic motion, and rectilinear motion, they are no longer able to confuse you.

The change in position of an item in relation to its environment in a specific time interval is referred to as a type of motion.
