What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force, making work easier. Examples include levers, pulleys, and inclined planes.

Front

What are the six types of simple machines?

Back

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

Front

How do inclined planes make work easier?

Back

Inclined planes reduce the amount of input force needed to move an object by allowing it to be moved over a longer distance at a lower height.

Front

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. It is used to lift or move loads.

Front

What is a wedge?

Back

A wedge is a simple machine that consists of two inclined planes joined together, used to cut or split objects.

Front

What is a screw?

Back

A screw is an inclined plane wrapped around a pole or rod, used to hold objects together or lift materials.

Front

What is a pulley?

Back

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

Front

What is the input force in a simple machine?

Back

The input force is the force applied to the simple machine to perform work, such as lifting or moving an object.

Front

How does a wheel and axle work?

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 loads.

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.
