Lever Flash Cards

Directions Add the label/info to the front of the flashcard for each level of organization. The second slide has the notes you will write on the back of the flashcard. Make sure you use bullets and that you write the notes exactly as they are given.

1st Class Lever

1st Class Lever The fulcrum is somewhere between the force and the load. Adds more force (advantage) depending on where the fulcrum is placed.

First Class Lever Examples: Your skull on the top of the spine, see-saws, scissors, crowbars, and your arms during a pushup.

2nd Class Lever

2nd Class Lever The load is somewhere between the fulcrum and the force. Adds more force (advantage).

Second Class Lever Very few examples of these in the body. Examples: Your foot when you stand on your toes, wheelbarrows, bottle openers, and your whole body during a pushup.

3rd Class Lever

The force is somewhere between the fulcrum and the load. Third Class Lever The force is somewhere between the fulcrum and the load. Increases movement speed. Force is NOT increased.

Third Class Lever Examples: Your arm when you lift a book, tweezers, a baseball bat hitting a ball, a fishing pole, and your upper body during a sit up.
