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.

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.

What is a lever?

Back

A lever is a rigid bar that pivots around a fixed point called the fulcrum, used to lift or move loads.

What is a wheel and axle?

Back

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

Front

What is a screw?

Back

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

Front

What is a wedge?

Back

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

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 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.
