• Pulley- grooved wheel with a rope or cable around it
• Screw- an inclined plane wrapped around a pole
• Wedge- slanting side ending in a sharp point used to split, lift, or hold
• Wheel and Axle- circular device with a rod, called an axle, through its center
Inclined Plane- allows things to move up or down it
