The amount of effort saved when using machines is called mechanical advantage (MA). Simple machines use mechanical advantage as a key property to their functionality, helping humans perform tasks that would require more force than a person could produce. We will use the lever as an example of a simple machine to illustrate the concept of mechanical advantage.

The division and multiplication of integers
Order of operations

Introduction to passive and active transport

In this unit we will learn how these factors can affect the output of a simple machine. We will also learn about the difference between ideal mechanical advantage (IMA) and actual mechanical advantage (AMA), and how to apply your knowledge to calculate the efficiency of various simple machines.

Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.

Part 1: Representation, comparison and ordering of integers on the number line
Part 2: Examples related to the representation and comparison of integers on the number line
Part 3: Common mistakes and misconceptions

What are simple machines? Simple machines are tools that make work easier. They have few or no moving parts. These machines use energy to do work with one movement. They make our work easier by letting us use less mechanical effort to move an object.

In this lesson you will learn about:

• Simple machines
• Be able to identify different kinds of machines
• Identify classes of levers and pulleys
• Determine mechanical advantage of a lever and pulleys
• Understand and determine the advantage of an inclined plane
• Describe and determine the advantage of a screw jack
• Describe and determine the advantage of a wheel and axel
• Describe and determine the advantage of a hydraulic press
