Study Notes

Work and Force

Work is equal to Force multiplied by Displacement
Force is a push or pull on an object, which can make objects move, stop, or change directions
Work is done on an object when a force causes it to move in the same direction as the force

Types of Simple Machines

Inclined Plane:
- Mechanical Advantage (MA) = slant length (slope) / height
- Has three components: Height (A), Length (B), and Slope (C)
Wedge:
- MA = slope / width
Screw:
- MA = circumference / pitch
- Circumference = 2π x radius or diameter
Wheel and Axle:
- MA = Wheel Radius / Axle Radius
Pulley:
- MA = Load / Effort

Friction and Displacement

Friction: a force that resists change in motion and makes it harder to move things
Displacement: a measure of how far out of place an object is, or the overall change in an object's position between two points
