# Frequently Asked Questions

**What is Conceptual Physics?**

The study of physics is concerned with understanding "the way the world works." By organizing our knowledge into a few fundamental concepts and equations, we can better understand the universe we live in.

*Conceptual Physics* is the name given to curricula designed to emphasize a strong understanding of the principles underlying physics. Physics is a quantitative science, of course, so there *is* math that supports the topics covered in this curriculum, and for most of those topics, no more than simple algebra is required to understand them. For this reason, most the material on this website *does* include slightly more math than a classic Conceptual Physics curriculum might. In my opinion, using simple algebra in a physics context both allows for a deeper understanding of the physics, and gives students a chance to practice and reinforce their mathematical skills.

**Where do the materials on this site come from?**

The multiple-choice problems on this site were written by Richard White. The curricular materials available on this site are based on materials used in my own teaching of the course.

Permission is given for Conceptual Physics teachers and students to use these materials as described in the Terms of Service.

**How does the whole Problem-a-Day thing work?**

The subscription-based "Problem-a-Day" is a great way of doing a little studying every day. You can sign up here to get a new problem delivered to you, once a day, in your email. There's no charge for the service, and you can unsubscribe at any time by clicking on a link in the emailed problems.

**Where can I find previously delivered problems from this site?**

A large number of problems, organized by subject area, are available in the Other Problems & Topics section of the website.
