Teach: Levers
Levers
In this lesson, you will learn about “levers,” one of the especially important topics in forces and motion. Rather than memorizing words alone, aim to explain the mechanisms and reasons in your own words.
Key Points
A lever is balanced when the products of the distances from the fulcrum and the applied forces are equal on both sides.
