Forces What is a Force? Push or Pull What does it do? Causes Motion How do we describe it? Size (magnitude) Direction
What are the 7 simple machines? • Lever • Inclined Plane Wedge Screw • Wheel and Axle Gear Pulley
Why do we use simple machines? • To make life easier! • Simple Machines change forces: change the direction change the size change both
How do they work? • Conservation of Energy Work and Energy are related • Scientific Definition of Work Work = Force x Distance distance in direction of force
Pulley Change Force Direction Same Force Size
