This video explores the angles found in parallel lines.

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.

In this course you will learn about:

1. Angles and lines
2. Angles formed between parallel lines.
3. Classifying polygons.
4. Quadrilaterals.

This online article delves into our the sun and planets were formed.

These four short online lessons will cover the following:

• The planets of the solar system
• Planet orbits in the solar system
• Gravity in the solar system
• Inner vs outer planets

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 short online lesson discusses the planet Jupiter.

This short online lesson explores the planet Mars.
