SIMPLE SIMPLE MACHINESMACHINES

What is a simple machine?

A simple machine is any device that only requires the application of a single force to work. a. A simple machine is a device for overcoming resistance at one point by applying force at some other point. b. Simple machines are important because they allow you to change the direction of the applied force or multiply a force.

What is a force?

A force is a push or pull. a. Forces are measured in Newtons (N). b. Weight is an example of a force since weight deals with the force of gravity. Weight is a measure of the force of gravity. c. One Newton is the weight of a small apple. d. A spring scale can be used to measure Newtons.

There are 6 types of simple machines.

effort – the force that is used to do work

Terms used with simple machines:

fulcrum- a pivoting or turning point

Terms used with simple machines:

load – the object that is being moved or lifted; typically the weight(force) of the object being moved; also called resistance or resistant force.
