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.

Use the dynamic worksheet to practice simplifying expressions with fractional exponents, rewriting them as radicals.

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

Three activities which illustrate the law of exponents.

This is a simple video which describes how indices problems are solved using simplified laws.

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.

An elaboration on how to use Newton's second law when dealing with multiple forces, forces in two dimensions, and diagonal forces.

An elaboration on some of the common misconceptions in dealing with Newton's Third Law. He also shows how to correctly and reliably identify Third Law force pairs.
