Work/Power/Simple Machines Test

Front

What does a simple machine do?

Back

A simple machine allows users to apply less force over a longer distance, reduces the amount of force needed to do work, and changes the direction of the applied force.

Front

What is an example of a wedge?

An axe is an example of a wedge.

Front

What is the formula for work?

Back

Work = force x distance.

Front

What is a pulley?

Back

A pulley is a simple machine that uses a wheel and a rope to lift or lower objects.

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

What is mechanical advantage?

Back

Mechanical advantage is the ratio of the output force to the input force in a machine, indicating how much a machine multiplies force.
