## Additional Learning Tools and Resources

Watching a presentation is a passive activity. Getting information is important ... but its not the destination or end point. Now that you've watched the video, its time to do something with the information you've heard. It's time to act on it. The resources below provide an opportunity to do this. We encourage learners to solidify their learning through the use of one or more of the following resources.

When it's time to practice solving Physics word problems, you'll get plenty of it at our Calculator Pad. You will find problems, answers, and audio-guided solutions. What more could you ask for? Give problems #3- #9 a try to improve your Coulomb's Law problem-solving skills.

Minds On Physics the App, Part 4, Missions SE8 and SE9 in the Static Electricity Module

Minds On Physics includes interactive questioning modules that provide a rigorous workout in careful reading, analytical thinking, and conceptual reasoning. Mission SE8 and SE9 from our Static Electricity module is all about Coulomb's Law. Put on your work-out clothes and get started.

Coulomb's Law Concept Builder

Coulomb's Law can be used as a guide to thinking about how a change in one variable effects other variables. This Concept Builder will give you plenty of chances to do that type of thinking.

This simulation allows you to alter the quantity of charge on two charged objects, to drag them around and change their separation distance, and to observe the force of attraction and repuslion. Now that's Coulomb's Law in action.

Sometimes you need a written reference to freshen up on what you're learning. And that written reference would be the Tutorial section of our website. The following two pages will be helpful complements to this video:
