Simple Machines Worksheet for students to define and understand basic mechanical devices.

Final Answer:
Inclined Plane: A flat surface tilted at an angle, used to lift objects with less effort over a longer distance.
Pulley: A wheel with a groove for a rope or cable, used to change the direction of force or lift heavy loads more easily.
Wheel and Axle: A wheel attached to a rod (axle); turning the wheel makes the axle turn, helping move or lift things with less effort.
Wedge: A triangular tool that splits, lifts, or holds objects apart by converting force applied to its thick end into sideways forces.
Lever: A rigid bar that pivots on a fixed point (fulcrum) to lift or move loads with less effort.
Screw: An inclined plane wrapped around a cylinder; turns to hold things together or lift materials slowly and steadily.
