Three ways to describe motion

1. Translatory motion:

Translatory motion is that in which all the particles of a body move through the same distance in the same time.

When a body moves along a straight line, it is called Rectilinear motion.

When a body moves along a curved line, it is called Curvinlinear motion.

2. Rotatory motion:

Rotatory motion is that in which a body moves about a fixed axis without changing its position.

3. Oscillatory motion:

Oscillatory motion is that in which a body moves to and fro about its mean position.

4. Periodic motion:

Periodic motion is that which repeats itself after regular intervals of time.

5. Repetitive motion:

Repetiive motion is that which occurs again and again.
