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.

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

Define 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 simple machine that consists of a wheel on an axle or shaft that is 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 consisting of a larger wheel attached to a smaller axle, allowing for easier movement of loads.

Front

What is a wedge?

Back

A wedge is a simple machine that is used to split, cut, or divide objects, consisting of two inclined planes.

Front

What is a screw?

Back

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

Front

How does a lever work?

Back

A lever works by applying force at one end, which pivots around the fulcrum to lift a load at the other end.

Front

What is the mechanical advantage of a simple machine?

Back

The mechanical advantage is the ratio of the output force produced by a machine to the input force applied to it.
