Motion And Its Kinds

Motion:

" When the body position changes with respect to its surrounding and time, then the body is said to be in Motion. "

Kinds Of Motion:

There are 8 different kinds of motion.

1. Translatory motion

2. Circular motion

3. Oscillatory motion

4. Vibratory motion

5. Repetitive motion

6. Periodic motion 

7. Multiple motion

8. Random motion

➡1. Translatory motion:

When all the particles of a body moves in the direction of motion, then that motion is known as Translatory motion.

➡Translatory motions are of two types.

a. Rectilinear motion

b. Curvilinear motion

➡a. Rectilinear motion:

When an object moves along a straight line then its motion is known as rectilinear motion.

Example- free falling bodies. 

➡b. Curvilinear motion:

When an object moves along a curved path then its motion is known as curvilinear motion.

Example- vehicles moving along a curved path.

➡2. Circular motion:

When an object moves in a circle then its motion is known as circular motion.

Circular motion is of two types

➡a. Rotatory motion

➡b. Revolutionary motion

➡a. Rotatory motion:

When an object without changing its position moves in a circular path then that motion is known as rotatory motion.

➡b. Revolutionary motion:

When a body changes its position while moving in a circular path then that motion is known as Revolutionary motion.

➡3. Oscillatory motion:

When an object

moves to and fro or back and forth along the same path then the motion  is known as oscillatory motion.

➡4. Vibratory motion:

Vibratory motion is similar to oscillatory motion. Here the object moves either in to and fro motion or in back and forth along with that the moving object undergoes change in shape or size is known as vibratory motion.

➡5. Repetitive motion:

When the object which is in motion repeats itself after certain interval of time then such motion is known as repetitive motion.

➡6. Periodic motion:

A repetitive motion, where the motion repeats itself after a fixed interval of time is known as periodic motion.

➡7. Multiple motion:

When an object processes two or more motion at the same time such motion is known as multiple motion.

➡8. Random motion:

When the motion of a body suddenly changes from one kind to another kind then such motion of a body is known as random motion.
