In this course you will learn about:
The two YouTube videos provide an indication of the differences in dairy farming between Tanzania and South Australia.
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.
This YouTube video delves into the impact that tourism can have on a country's economy.
This YouTube video delves into the impact that tourism can have on the environment.
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.
This YouTube video explains how river basins are formed.
This 20 minute YouTube video explores the differences between small and large scale agriculture and the uses of each.
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.
