1st Class Levers

A 1st class lever is like a seesaw on a playground! It has three important parts:

• Fulcrum: The center point that the lever pivots on
• Effort: The force you apply to one end of the lever
• Load: The object or resistance at the other end that you're trying to move

When you change the length of the effort arm or load arm, you can make it easier to lift heavy things (force multiplication) or make things move faster (speed multiplication)!
