Classification of Motion
Motion can be classified into various categories based on different criteria. Here are some common classifications of motion:
Uniform Motion
- Uniform motion is when an object travels in a straight line at a constant speed.
- In uniform motion, the object covers equal distances in equal intervals of time.
Non-Uniform Motion
- Non-uniform motion is when an object travels in a way that its speed or direction changes.
- The object covers unequal distances in equal intervals of time in non-uniform motion.
Rectilinear Motion
- Rectilinear motion is when an object moves along a straight line.
- This type of motion can be uniform or non-uniform.
Circular Motion
- Circular motion is when an object moves in a circular path around a fixed point.
- The object has a constant speed but constantly changes direction in circular motion.
Periodic Motion
- Periodic motion is when an object repeats its motion after a regular interval of time.
- Examples of periodic motion include the swinging of a pendulum or the motion of a vibrating spring.
Oscillatory Motion
- Oscillatory motion is a type of periodic motion where an object moves back and forth around a central point.
- The motion of a swing or a vibrating guitar string is an example of oscillatory motion.
Irregular Motion
- Irregular motion is when an object moves in a random or unpredictable manner.
- This type of motion does not follow a specific pattern or direction.
Understanding the classification of motion helps in analyzing and describing the movement of objects in a structured way. It also allows for a better understanding of the principles of physics related to motion.

Motion can be defined as a phenomenon where the position of an object is changed over a time. A frame of reference is attached to an observer, and the change in location of the body relative to that frame is measured as time passes. Displacement, distance, velocity, acceleration, speed, and time are all mathematical words used to describe motion. An object is said to be at rest or motionless or immobile or stationary, or to have a constant or time-invariant location with respect to its surroundings if it does not change relative to a particular frame of reference. Absolute motion cannot be defined since there is no absolute frame of reference. As a result, everything in the cosmos may be thought of as being in motion. As motion can be applied to various systems of physics such as radiation, space-time, etc. and to shapes, images and boundaries as well, the motion can be said to change positions and configurations in space continuously.



Types of Motion:
There are certain types of motion based upon state of motion, direction, etc. The types of motion are:

1 Oscillatory motion
2 Rotational motion
3 Translational motion
4 Uniform motion
5 Non- uniform motion
6 Periodic motion
7 Circular motion
8 Linear motion
