Explain motion.

Hint: This question is based on the concept of the motion. Thus, we will define the term motion, the types of motion and their applications or the usage. There are different types of motion. And the motion is classified on the basis of periodicity, path and the speed of the object/body. Path – circular, oscillatory, vibratory, translator and rotator. Periodicity – periodic and non-periodic. Speed – uniform and non-uniform.

Complete answer:
The rate of change in the position of the body/object is called the motion.
There are many types of motion. The motion along a straight path is called the linear motion. One of the types of linear motion is called the rectilinear motion. The rotational motion or the circular motion is the motion along a circular path. The change in the position of the object/body from point to the other through spinning is called the translational motion. The periodic motion or the oscillatory motion or the vibratory motion is a to and fro motion that involves the vibrations.

The examples of these motions are: In case of the motion of a swing, swing moves to and fro. As the cyclist moves on a plain road and not on a circular path, the motion will be linear. The stone falls along a linear path. When the string of a sitar is plucked, the string starts to vibrate. In case of the pendulum of a wall clock, the pendulum moves to and fro. A spinning ball spins and changes its position concerning time.

Note: The oscillatory motion is sometimes considered different from the vibration motion according to the situation. For example, in the case of plucking of a sitar string, the motion is considered to be vibration and not oscillatory.
