This app solves physics problems for you and it shows you how it does it.You don't have to deal with the formulas and to do any calculations. The app has a list of topics that it can handle. You click on the topic of your problem, and that starts a chat. The app asks you questions about the givens of the problem and what you have to find out (the targets). It then displays the solution and the details of the derivation. It also converts the units of the givens and the results (if you want to).
PROBLEM: A rock is tossed straight up at 50 feet per second. How much time will it take to reach a point 4 meters above its starting point? (Neglect air resistance.)
How it works:
You browse the table of contents (screenshot 1, above). Topic 2.2 (Free Fall One Segment) matches the situation of the problem. You click on it, and the chat starts.
Screenshot 2 is a record of the chat. Your answers are shown in the right end of the boxes.
Screenshot 3 displays the givens and the solutions (the targets and other things that the app could calculate.) It also shows a conversion that you wanted to do.
Screenshot 4 displays the details of the derivation.
This innovative app was prepared by a veteran physics professor and an experienced computer scientists. Its aim is to help students of algebra-trig based introductory physics. It simulates and illustrates how physicists solve problems.
It is expected that by participating in such chats, students should pick up what type of questions physicists ask themselves as they solve physics problems. Quite often, knowing what to ask is half of the solution. This skill can be used also for any physics topics.
With this app's help you'll be able to understand how to solve Physics 1 and 2 problems, like those that are given at the end of chapters in most General Physics textbooks. By going over the details of the solutions you'll develop insights about the meanings of the formulas and how they are used.
This app is helpful when:
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.

Once you have completed the basic questions from Stage 1 to Stage 4,
try to solve the challenging problems on the Final Stage !
If you can't solve a ploblem, you can check the hint of the question or ask the answer to your friends via Twitter.
'Angles?' contains following contents:
-The sum of the Angles of a triangle
-Exterior angle of a triangle
-The sum of the Angles of a quadrilateral
-The sum of the Angles of a polygon
-Alternate segment theorem
* Increasing levels of difficulty Easy > Medium > Hard > Expert
* Great for testing your child's competency with math story problems
Math word problems allow kids of all ages to apply what they've learned in school to real-world situations. Word problems build critical problem-solving, higher-order thinking, and reasoning skills. A great in-class teaching tool for teachers and students!
TYPES OF MATH WORD PROBLEMS:
* One step & extra details
* Two step & extra details
* One step w/ regrouping and no regrouping
* One step w/ 3 digits
* Two step w/ regrouping and no regrouping
*"Lite" version limits access to first two story groupings (for each type of problem). "Pro" version allows unlimited access to all math word problems + free story add-ons available constantly.
Matrix operations: echelon form, reduced echelon form, inverse, inverse by adjoint, adjoint matrix, characteristic polynomial, determinants up to 5x5, eigenvalues and eigenvectors, nullspace, spanning set, rowspace, range, left nullspace, wronskian, LU factorization, Hessenberg form, Hessenberg polynomial, Householder transform, QR factorization, and least squares solutions.
Single variable equation operations: differentiation, integration, multiply, and root finding.
Parametric equation operations: gradient, is gradient of, curl, and divergence.
Differential Equation operations: Solve second order differential equation, and solve second order initial value problems.
Please feel free to email me if you have any suggestions for new problem types or are having problems with the program. I'll issue updates as soon as I can with new content/fixes based on user feedback.
