My Study of Simple Machines By: Grant Davey

Gear a toothed wheel that engages another toothed mechanism in order to change the speed or direction of transmitted motion Me and my partners built a gear train.

Inclined Plane A ramp that uses less effort by traveling a greater distance. Me and my partners built a ramp.

Pulley A rope and a wheel that’s used to lift things. Me and my partners built a pulley

Screw A nail that has a inclined plane wrapped around it.

Wheel and Axle A wheel and axle is a lever that rotates in a circle around a center point. Me and my partners built a car/ wheel and axle

Wedge A wedge is a triangular shaped tool, that has a sharp edgetriangular

Lever A lever is a tool that you need effort to use. Me and partners built a catapult

Machine A tool that magnifies effort.

Work Effort in doing or making something.

Force A powerful effect or influence.

Mechanical Advantage How many times effort is multiplied by a machine.
