Question
Which type of motion is represented by the plastic ruler shown below?
- Circular
- Translatory
- Rotatory
- Vibratory
Hint:
When a body moves to and fro about its mean position is called vibratory motion.
The correct answer is: Vibratory
The plastic ruler as shown in the figure moves up and down at regular intervals of time. Hence, it is said to be in vibratory motion.
