Machines are tools that help people do work more easily. In physics, you do work anytime you use force to move an object. Skateboards, cars, bikes, shovels, boats, doors, light switches, and stairs are all machines. Simple machines are the most simple tools. There are six of them: LEVER WHEEL & AXLE PULLEY INCLINED PLANE SCREW WEDGE
Students learn the basic principles of simple machines and explore everyday uses. Simple machines are "simple" because most have only one moving part. "Work" is only done when something is moved (displaced) by a force (push or pull).
1. Pass out What are Simple Machines? to the class and/or display the information to the class on an overhead. 2. Ask the class for examples of simple machines they have seen. Lead a discussion on why they’re important or how life would be different if we didn’t have simple machines. 3.
11 sie 2014 · This document summarizes the six types of simple machines: lever, pulley, wheel and axle, inclined plane, wedge, and screw. It defines simple machines as tools that make work easier and faster by changing the direction or magnitude of force.
This unit focuses on the scientific concept of simple machines and how they reduce the effort needed to perform certain tasks. Students are familiar with several simple machines through exposure in day-to-day life.
THE SIX SIMPLE MACHINES. An inclined plane is a slanting surface connecting a lower level to a higher level. By rolling or pushing an object up it, you can move the load with less work. A ramp is a great example of an inclined plane. A wedge is an object with at least one slanting side, ending in a sharp edge.
simple machines can be found in familiar devices. One or more simple machines may be combined to form a complex machine. Understanding how various machines work will help students to choose appropriate machines and use them properly. Key words: axle, block and tackle, complex machine, distance, energy, first-
