Motion and it's Types

Trains are an excellent mode for commuting long distances

As we board a train from a station, it starts moving and helps us reach our destination

As the train changes position while moving from one station to another with respect to time, it is said to be in Motion

Any object that changes its position with respect to time is said to be in Motion

Depending on the type of path or the way an object moves, Motion can be classified into different types

Let's discuss the types of motion

The different types of Motion are namely,

Let us first discuss Translatory Motion

When a car moves on a road, each and every part of the car including the rear-view mirror, doors, move along with it simultaneously

In such a case, it can be said that each and every part of the car covers the same distance in the same interval of time

The motion of a body in which all the particles of a body move through the same distance at the same time is called Translatory Motion

Translatory Motion can be further classified into two types such as Linear Translatory and Curvilinear Translatory

When a body undergoing Translatory Motion moves in a straight line, it is said to be in Rectilinear Translatory Motion

For example, when a car moves in a straight road, it is said to be in Rectilinear Translatory Motion

But if the ball is thrown at an angle to another person, it does not follow a straight path

Instead, it moves along a curved path

When a body moves along a curved line, the motion described by the body is called Curvilinear motion

An athlete running in a curved track is said to be in Curvilinear Motion

Let us now discuss Rotatory Motion with an example

If we spin a spinning top with our fingers, it starts to rotate about an imaginary line passing through its centre, known as its axis

In this case, we can observe that parts of the top are not changing their position with respect to its axis

The movement of an object about an axis is known as Rotatory Motion

Now let us discuss Oscillatory Motion

The motion of a body undergoing repeated to-and-fro motion about a fixed point is called Oscillatory Motion

For example, a little girl swinging on a swing moves back and forth in the air

The motion of a swing repeats itself within a certain time interval, therefore is said to be in Oscillatory Motion

Now lastly, let's discuss Circular Motion

As a child, it was common to swing a stone tied to a rope in circles

The stone used to fly over our head in circles, or better said along a circular path

The motion of an object moving in a circular path with a fixed distance from the centre of the circle is known as Circular Motion

Revision

Any object that changes its position with respect to time is said to be in Motion

The motion in which all the particles of a body move through the same distance in the same time is called Translatory Motion

A body moving in a straight line is said to be in Rectilinear Translatory Motion. When it moves in a curved path it is said to be in Curvilinear Translatory Motion

The movement of an object about an axis is known as Rotatory Motion

If a body is undergoing repeated to-and-fro motion about a fixed point, it is said to be in Oscillatory Motion

The motion of an object moving in a circular path with a fixed distance from the centre of the circle is known as Circular Motion
