Lever

(a rigid segment); the bones are assumed to be rigid, while in reality they're not

Fulcrum

the joint; the center of motion and location of the axis of motion

Force

the pull of a muscle

Resistance

the weight being moved (can be a body part)

Mechanical Advantage

the ease with which the resistance can be moved

Longer lever arm of the force

less force is needed to move the resistance

Longer lever arm of the resistance

more force is needed to move the resistance

First Class Levers

Fulcrum is located between the force and the resistance

Second Class Levers

Force and Resistance are on the same side of the fulcrum; resistance is closer to the fulcrum; better advantage

Third Class Levers

Force and Resistance are on the same side of the fulcrum; force is closer to the fulcrum; better mobility
