Teeter-Totter

A teeter-totter is a long, balanced plank supported at its center, called the fulcrum. When one end is pushed down, the other rises, functioning as a simple example of leverage. Its movement depends on the weight and position of objects on each side; heavier or closer objects exert more influence, causing the plank to tilt. This demonstrates principles of physics like force, balance, and lever mechanics. Teeter-totters are commonly found in playgrounds, providing fun while illustrating basic physics concepts in action.
