Definition of Motion

Motion by definition is a change in the position of a body with time with respect to a reference point. Motion exists in various forms and occurs in all the three states of matter (solids, liquids and gases). These various forms are;  random, translational, rotational and oscillatory motion.

Some examples of motion are;

  1. The movement of the earth round the sun
  2. The rotation of the earth about its axis
  3. An aeroplane flying in the sky
  4. A boy walking or running


Types of Motion

A. Random motion

Random motion is the movement of a body in a zigzag or disorderly manner with no specific direction as shown in the diagram below. Some examples of this kind of motion are; the motion of dust particles in the air, the motion of smoke particles, the motion of butterfly, etc.
