Applying Newton's first law to answer some true/false statements about why objects move (or not).

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.

Figuring out the acceleration of ice down a plane made of ice.

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.

In this online lesson you will learn how to compare measurements that have different units.

In this unit you will learn how to convert between common metric units of measure.
