- LOAD: The object or resistance that the lever is designed to move or lift.
- FULCRUM: The pivot point around which the lever rotates.
- FORCE: The effort applied to the lever to move the load.
- FIRST CLASS LEVER - My observations: The fulcrum is positioned between the load and the force. This arrangement can change the direction of the force and may provide a mechanical advantage depending on the distances from the fulcrum.
- SECOND CLASS LEVER - My observations: The load is located between the fulcrum and the force. This setup always provides a mechanical advantage, making it easier to lift heavy loads with less force.
- THIRD CLASS LEVER - My observations: The force is applied between the fulcrum and the load. This configuration increases speed and distance of movement but requires more force than the load being moved.
