What are the six types of simple machines?

Back

The six types of simple machines are: lever, wheel and axle, pulley, inclined plane, wedge, and screw.

Front

Define a lever.

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum. It is used to lift or move loads.

Front

What is a wheel and axle?

Back

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects with less effort.

Front

Define a wedge.

Back

A wedge is a simple machine that is a triangular-shaped tool used to split, lift, or hold objects apart.

Front

What is a screw?

Back

A screw is a simple machine that consists of a cylindrical shaft with a helical ridge (thread) that converts rotational motion into linear motion.

Front

How does a pulley work?

Back

A pulley is a simple machine that uses a wheel and a rope to lift or lower objects, changing the direction of the force applied.

Front

What is mechanical advantage?

Back

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied, indicating how much a machine multiplies force.

Front

What is a compound machine?

Back

A compound machine is a device that combines two or more simple machines to perform a specific task more efficiently.
