Does anyone know of something like this?

It's similar to a formula sheet, but its just if they are directly/inversely proportional.

For example:

Power is directly proportional to current and voltage
Gravitational force is inversely proportional to radius

I don't know any formula sheet. but you need to be careful. either proportional or inversely proportional, sometimes there is a twist. for example, gravitational force is inversely proportional to the SQUARE of the distance between two objects. That distance could be the radius, (like that of the earth), or something else. The test plays tricks with details like these.
