WHAT IS A SCREW?

A screw is really a type of inclined plane. The inclined plane is wound around a post. Screws can be used to lift things. Examples of screws include some car jacks and some piano stools in addition to the screws we typically buy at the hardware store.

WHAT IS A WEDGE?

A wedge combines two inclined planes back to back. Wedges move objects apart by being forced under or between them. Wedges change the direction of force applied to them

WHAT IS AN INCLINED PLANE?

An inclined plane consists of a tilted flat surface. The inclined plane allows us to move objects upward more easily than lifting the object directly. Raising an object to a particular height requires a certain amount of work.

WHAT IS A PULLEY?

A pulley is a grooved wheel that spins on a fixed axis with a rope or chain moving over the wheel.

WHAT IS A WHEEL AND AXLE?

A wheel and axle involves a circular rotating part (the wheel) that turns around a shaft (the axle). Turning one part turns the other.
