Simple Machines

Front

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.

Front

What are the six types of simple machines?

Back

lever, inclined plane, wedge, screw, pulley, and wheel and axle.

Front

How does a simple machine make work easier?

Back

A simple machine makes work easier by increasing the distance through which force is applied, changing the direction of applied force, or multiplying the force of the energy applied.

Front

Inclined Plane

Back

A flat surface that is tilted at an angle to help raise or lower objects.

Front

Lever

Back

is a rigid bar that pivots around a fixed point called the fulcrum, 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 split or cut objects.

Front

What is a screw?

Back

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 pulley?

Back

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 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 mechanical advantage?

Back

is the ratio of the output force produced by a machine to the input force applied, indicating how much a machine multiplies force.
