Kinds of Motion For Class 9 | Physics

Rest:

A body is said to be at rest when it does not change its position with respect to their environment and time. For example house, tower, tree etc.

MOTION:

A body is said to be in motion when it changes its position with respect to environment and time.
For example moving car, walking man etc.

TYPES OF MOTION :

  • Linear Motion
  • Circular Motion
  • Rotatory (or Rotational ) motion
  • Oscillatory (or Periodic ) motion

Linear Motion:

When a body moves along a straight line ,then the body is said to be in linear motion.

Circular Motion:

When a body moves along a circular path ,then the body is said to be in circular motion.

Rotatory Motion:

When a body moves on its on axis , then the body is said to be in Rotatory motion.

Oscillatory Motion :

When a body repeats its path continuously , then the body is said to be in oscillatory motion.
