Inclined Planes and Pulleys
Term | Definition |
---|---|
Simple Machine | Device that makes work easier, often by reducing the amount of effort force needed to move an object. |
Inclined Plane | A ramp or slope that reduces the force needed to move objects up and down heights; a simple machine. |
Pulley | A device consisting of a wheel over which a rope or chain is pulled in order to lift heavy objects; a simple machine. |
Load | The object to be moved using a machine. |
Force | a push or pull that can change the motion of an object, measured with a spring scale in Newton (N) units. |
Movable Pulley | A pulley attached to the object to be moved reduces the force needed to move the object; a simple machine. |
Fixed Pulley | Attached to a structure and does not move; changes the direction of the effort force used to lift a load; a simple machine. |
Pulley System | a combination of fixed and movable pulleys. |
Spring Scale | a tool that measures a pulling force by the tension on a spring; the force is measured in Newtons. |
Newton | Unit of measurement for forces, measured using a spring scale. |
