Let us consider, that you are sitting on your sofa watching TV, think about whether you are in motion or at rest. Clearly, you are at rest. But let us re-evaluate the situation, we all live on the earth and it is continuously moving, so are you in a state of motion or at rest? Finding the answer to such perplexing questions can be confusing. Before you gear up to find the answer to such complex questions, you must gather thorough knowledge about various types of motion. Here is a blog that aims to elucidate the same with examples that can help you in various competitive and entrance exams.

What is Motion?
The free movement of a body with respect to time is known as motion. For example-the fan, the dust falling from the carpet, the water that flows from the tap, a ball rolling around, a moving car etc. Even the universe is in continual motion. Are all these motions the same? Is the motion of a pendulum the same as that of a moving car or train? There are various types of motions that are happening around us and they can be basically distinguished on the basis of:

Types of Motion
As per physics and mechanics, there are mainly 4 types of motion, i.e.
- Rotary Motion: A special type of motion in which the object is on rotation around a fixed axis like, a figure skater rotating on an ice rink.
- Oscillatory Motion: A repeating motion in which an object continuously repeats in the same motion again and again like a swing.
- Linear Motion: A one-dimensional motion on a straight line, like an athlete running on a straight track.
- Reciprocating Motions: A repetitive and continuous up and down or back and forth motion like a needle in a sewing machine.

There are also different other types of motion as per directions or as per state of motion.
Types of motion as per state
- Uniform Motion
- Non-Uniform Motion
Types of motion as per direction
- One Dimensional Motion
- Two Dimensional Motion
- Three Dimensional Motion
Other types of motion
- Translational Motion
- Periodic Motion
- Circular Motion
Here is a chart on types of motion:
Other Types of Motion
Below we have explained the major 7 types of motion as per Physics:
Oscillatory motion is simply the motion that an object does by repeating the same movement again and again. Oscillatory motion would keep on moving forever when there is an absence of friction but in our real world, the motion eventually stops and comes to an equilibrium. Some of the best examples of Oscillatory Motion are:
- A swinging swing
- The motion of a pendulum
- A boat tossing up and down a river
- The tuning fork
Rotational motion can be defined as when an object moves along its axis and all the parts of it move for a different distance in a given period of time. Thus, if an object is under rotational motion all of its parts will move different distances in the same interval of time. As an example, merry-go-round, blades of a fan, blades of a windmill etc.

When all the parts of an object move the same distance in a given time is known as transitional motion. For example, a cycle moving on a track, a man walking on the road, birds flying in the sky.
Mainly, there are two types of translation motion which are explained below:
|Curvilinear Motion||Rectilinear Motion|
|When an object moving in translational motion follows a curved path it is known as Curvilinear motion.||An object moving in translation motion opts a straight-line path, then it is known as Rectilinear motion.|
|Example: A stone thrown up in the air||Example: A train moving on a straight track or a car moving on a straight road|

A motion that repeats itself after equal intervals of time is known as periodic motion. Commonly, the objects under this motion are mostly in the to and fro motion. Here are a few examples of periodic motion.
- A moving pendulum
- Hands of a working clock
- the earth rotating on its axis, etc.

When an object is constantly moving in circular a path it is called circular motion. It circular motion, the speed of the object should be constant. A few examples of circular motion are:
- Movement of the earth on its axis
- a bicycle or a car moving on a circular track of park
- the motion of the moon around the earth etc.

Linear motion can be defined as the movement of a body on a straight line without any deviation. Important examples of linear motion are:
- An athlete running on a straight track of a park
- a bullet shot from a pistol
A body is said to be in a state of uniform motion when it covers an equal amount of distance in equal intervals of time. In such cases, if we represent the motion on the graph, it would be a straight line. Examples of uniform motion are:
- A car moving on a straight road at a steady speed
- a flying aeroplane at a set height at a constant speed, etc

Non-uniform motion can be defined as when a given body is covering unequal distances in a set and given intervals of time. If you will represent the path of a body moving in non-uniform motion on a graph, it will be a curved line. Examples of non-uniform motion are:
- a man walking on the road
- a freely falling body
- a train moving at various speed limits, etc.
General motion is the most common type of motion in sport and physical exercise.
All motions are relative to a reference frame. Saying that a body is at rest, or that it is not in motion, simply means that it is being described in relation to a frame of reference that is moving along with it.
