Write one example for each of the following type of motion. Periodic

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Periodic Motion**: Periodic motion is defined as motion that repeats itself after a fixed interval of time. This means that the object returns to its original position after a certain period.

2. **Identifying an Example**: One of the best examples of periodic motion is a pendulum. A pendulum swings back and forth in a regular pattern, returning to its starting position after a specific amount of time.

3. **Describing the Pendulum's Motion**: When a pendulum is set into motion, it moves from its mean position (the center) to one extreme position (either to the left or right), then back through the mean position to the opposite extreme position, and finally returns to the mean position. This entire movement constitutes one complete cycle.
