## This is a free database of solved physics problems

1. You solved a problem and you want to check your solution.
2. You know how to solve the problem in principle, but you want someone else to go through the chores (a physics problems calculator).
3. You want to observe how an expert solves physics problems, and learn from these examples.
4. You just want the problem solved.
Q: Can the app solve any possible “end of chapter” problem for a situation listed in the table of contents?A: In tests, the app has successfully solved thousands of “end of chapter” problems. It should solve any problem whose variables are directly linked to the symbols of the formulas that it uses.
In some cases, some pre-processing by the user is needed. For example, if a formula uses area as one of its variables, and the given is the radius of a circle, the user will have to calculate the area and provide it to the app.
Also, in complex problems that are combinations of more basic ones, the user will have to dissect the complex problem into basic ones, and the app should be able to solve them one by one.Physics is sophisticated, programming is intricate, and mistakes happen. So, ALWAYS check the solutions provided by this app, before using them. TOPICS HANDLED BY THE APPMotion at Constant Velocity in One Dimension

## We understand Physics – it means that we can solve physics problems.

used before. This paper describes how the Companions cognitive architecture ( Forbus & Hinrichs 2006) models example use in solving AP Physics problems.
