What is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum.

What is a wheel and axle?

Back

A wheel and axle is a simple machine made up of a larger wheel attached to a smaller axle, allowing for easier movement.

Front

What is a wedge?

Back

A wedge is a simple machine that is used to split or cut objects apart.

Front

What is a screw?

Back

A screw is a simple machine that converts rotational force into linear motion, often used to hold objects together.

Front

How do simple machines make work easier?

Back

Simple machines make work easier by decreasing the amount of force needed to complete a task.

What is work in physics?

Back

Work is done whenever a force moves an object a distance.
