SIMPLE MACHINES - LEVER

SIMPLE MACHINES - LEVER. SIMPLE MACHINES - LEVER. A lever is a rigid bar that rotates around a fixed point called the fulcrum. The bar may be either straight or curved. In use, a lever has both an effort (or applied) force and a load (resistant force). . SIMPLE MACHINES - LEVER.

Work, Machines, and Energy

Work, Machines, and Energy. Work and Power. Work is done if (1) an object moves, and (2) if a force acts in the same direction that the object moves. Work = Force times distance W = (F)(d) Work is measured in units called Joules (J).
