Question

Which of these is an example of oscillatory motion?​

• A. Motion of an electric fan
• B. Motion of Earth around Sun
• C. Motion of pendulum of a wall clock
• D. Motion of an apple falling from tree

Answer 1

The correct option is C Motion of pendulum of a wall clock

• A fan sweeps complete circle on its own axis, thus it is an example of rotational motion.​

• Earth sweeps one complete circle with sun at centre in 1 year, thus it is an example of circular motion.​

• The pendulum move from one point to other and again trace its path between same two points, thus an example of oscillatory motion.​

• An apple moves in straight line while falling from the tree. It is an example of linear motion.​
