Question

A stone falls freely from a cliff. Its motion is

• A. Translatory
• B. Periodic
• C. Rotatory
• D. Random

Answer 1

The correct option is A

Translatory

The explanation for the correct answer.

1. A stone freely falling from a cliff shows a translatory motion.
2. If an object moves as a whole from one place to another, so that each part of it moves the same distance in a given time then the object is said to be in translatory motion.
3. A freely falling body is an example of translatory motion.

The explanation for the wrong answer.

1. Motion repeated at an equal interval of time is called periodic motion.
2. If a body moves along a fixed axis or point it is said to be in a rotatory motion.
3. When an object has no specific path and repeatedly changes its position than the object is said to be in random motion.

Hence, option (A) is the correct answer.
