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 are the six types of simple machines?

Back

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

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 lever?

Back

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

Front

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 pulley?

Back

A pulley is a simple machine that uses a wheel and a rope to lift or lower objects.

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 or lift materials.

Front

What is a wedge?

Back

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

Front

How does a lever work?

Back

A lever works by applying force at one end to lift a load at the other end, with the fulcrum providing a pivot point.

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.
