Work and Simple Machines

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as Work = Force x Distance.

Front

What is a simple machine?

Back

A simple machine is a device that makes work easier by allowing us to apply a smaller force over a greater distance.

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

How does an inclined plane help in doing work?

Back

An inclined plane allows you to lift heavy objects by spreading the work over a longer distance, reducing the amount of force needed.

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.

Front

What is the purpose of a pulley?

Back

A pulley is used to change the direction of a force, making it easier to lift heavy objects.

Front

What is a wedge?

Back

A wedge is a simple machine that is used to split or cut objects apart, 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 wheel and axle work?

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 heavy loads.

Front

What is mechanical advantage?

Back

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