What is a simple machine?

Back

A simple machine is a device that makes work easier by allowing us to apply force in a more efficient way. Examples include levers, pulleys, and inclined planes.

What are the six types of simple machines?

Back

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

Front

What is a pulley?

Back

A pulley is a simple machine that consists of a wheel on an axle or shaft that is designed to support movement and change the direction of force.

Front

What is a wheel and axle?

Back

A wheel and axle is a simple machine that consists of a larger wheel attached to a smaller axle, allowing for easier movement of objects.

Front

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

What is a wedge?

Back

A wedge is a simple machine that is used to separate two objects or portions of an object, often by applying force to one end.

Front

What is a screw?

Back

A screw is a simple machine that consists of a spiral inclined plane wrapped around a cylinder, used to hold objects together or lift materials.

Front

How does a lever work?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum, allowing for the amplification of force.

Front

What is the purpose of simple machines?

Back

The purpose of simple machines is to make work easier by changing the amount of force needed, the distance over which the force is applied, or the direction of the force.

Front

What is an example of a simple machine in everyday life?

Back

Examples of simple machines in everyday life include a seesaw (lever), a ramp (inclined plane), and a bicycle (wheel and axle).
