Choose the equation(s) you have access to from class or the one(s) you want to use.
Note that for ΔE, Efinal relates to KE and Einitial relates to PE.
In reality, these could be the other way around, but I haven't accommodated for that case yet.
Enter the values you were given.
Type any text for the variable's value that you wish to solve for.
Click Solve.
It is possible that you can select a set of equations and values that make it impossible to solve a
given question, so take care.
At present, the Calculationer will solve every formula it can while it works through to a
solution. Some of those calculations may not be necessary to solve the main problem. For example, the
Calculations often solves for weight just because it has mass and gravity. You may not need the weight.
The solver may "hang" for a few seconds before giving up. Be patient if nothing happens right away.
Use the random question generators for practice problems.
Sometimes the multi-step question generator produces single-step problems to keep you on your toes.
