Simple Machines

Front

What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force, making work easier.

Front

What are the six types of simple machines?

Back

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

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.

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 pulley?

Back

A pulley is a wheel on an axle designed to support movement and change the direction of force, often used to lift heavy objects.

Front

What is a wedge?

Back

A wedge is a device that tapers to a thin edge, used to separate or hold objects apart.

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

How does a simple machine reduce the amount of force needed to do work?

Back

A simple machine allows users to apply less force over a longer distance, making it easier to perform work.

Front

What is the function of a screw as a simple machine?

Back

A screw converts rotational force into linear motion, allowing it to hold objects together or lift materials.

Front

What is the mechanical advantage of using simple machines?

Back

Mechanical advantage is the factor by which a machine multiplies the force put into it, making tasks easier.
