Question

Define the following:
[a] Rotatory
[b]oscillatory

Answer 1

Answer:

[a] Rotatory motion is the motion that occurs when a body rotates on its own axis. A few examples of the rotatory motion are as follows: The motion of the earth about its own axis around the sun is an example of rotary motion.

[b] A motion repeating itself is referred to as periodic or oscillatory motion. An object in such motion oscillates about an equilibrium position due to a restoring force or torque.

Answer 2

Rotatory Motion

Rotatory motion is the motion that occurs when a body rotates on its own axis.  A few examples of the rotatory motion are as follows :

• The motion of the earth about its own axis around the sun is an example of rotary motion.
• While driving a car, the motion of wheels and the steering wheel about its own axis is an example of rotatory motion.

Oscillatory Motion

Oscillatory motion is the motion of a body about its mean position. A few examples of  oscillatory motion are  :

• When a child on a swing is pushed, the swing moves to and fro about its mean position.
• The pendulum of a clock exhibits oscillatory motion as it moves to and fro about its mean position.
• The string of the guitar when strummed moves to and fro by its mean position resulting in an oscillatory motion.
