Simple Machines, Work, and Mechanical Advantage

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

Front

What is a pulley?

Back

A pulley is a simple machine that consists of a wheel on an axle or shaft, used to lift or lower 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.

Front

How does an inclined plane reduce effort?

Back

An inclined plane reduces effort by allowing a load to be raised over a longer distance with less force.

Front

What is work in physics?

Back

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