HyperPhysics Description: |

**is an educational resource about physics topics. The information architecture of the website is based on trees that organize topics from general to specific.**

*HyperPhysics**HyperPhysics*is hosted by Georgia State University, which estimates that

*HyperPhysics*has over 3 million users per year.

The hit rate reached about 50 million file hits per year in the fifth year and logging was suspended. Informal statistics from the server log indicate about 15 hits per user on average, so 50 million hits translates to over 3 million users per year.

Search engines give over 200,000 links to HyperPhysics, mostly from educators or educational institutions.

It is started by

HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or “cards”, true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network.

**Physics Homework Help!**

*by HyperPhysics.info*

*A powerful recipe for solving even the most confusing physics problems:*

**STEP 1. What is my unknown?**

What variable am I trying to find?

What are its units?

What is its symbol(s)?

*Do not pay attention to the values and/or numbers the problem is providing just yet.*

**STEP 2. What physics is occurring?**

What principles of physics are occurring in the problem? This is a simple question if you are working a problem from a text book:

*its the name of the chapter your in!*If you dont know where to start, just start searching portions of the question in HyperPhysics.info. Even seemingly general words like mass, equilibrium, and rate can be very helpful in locating descriptions and diagrams. You may even stumble onto an example of the exact problem if your lucky.

**STEP 3. What are my equations?**

Search your textbook or HyperPhysics.info for the governing equations? Do the governing equations include your unknown variable? If not, you may need some geometric information or need to make other assumptions to solve the problem.

**STEP 4. Number of equations = number of missing variables?**

Once you have located your variable in one of the governing equations fill in the values you know. If you have one equation and one unknown, just finish your algebra and your done. Your number of equations will be equal to the number of missing variables in order to solve the problem(that includes your primary unknown of course). If you have too many variables, you may have used the wrong formula or simply need more equations.

**STEP 5. Can your thought process be followed?**

Most good physics teachers believe in partial credit. This is due to the complex, multi-step nature of the problems. If you would like an opportunity to receive points for your wrong answers you need to make sure that the grader can follow your work. This includes showing your units, equations, and assumptions throughout the problem. Don't forget to box or circle your answer.
