Give two examples of periodic motion.

Periodic motion refers to a type of motion that occurs repeatedly in a fixed interval of time, maintaining a consistent pattern. It is commonly observed in everyday life where objects move back and forth or in cycles, returning to their initial position after a specific duration.

Give two examples of periodic motion:

1. Motion of the pendulum of a clock - The pendulum in a clock swings back and forth at regular intervals, making it a classic example of periodic motion.
2. Motion of a child on a swing - When a child swings, they move forward and backward in a repetitive manner, demonstrating periodic motion.
