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, pulley, screw, and wedge.

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 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 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 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. It can change the direction of the force applied.

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

What is a wedge?

Back

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

Front

How does a lever work?

Back

A lever works by applying force at one end, which is transferred to the 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.
