direction. An emf will be produced to oppose this change in current, so the emf will be clockwise (if we are looking at the loop somewhere where

Hey guys. I've noticed that there are a decent number of "tricks" in physics problems that can help boost speed and efficiency. An example of which would be:
- One mass colliding with an identical mass at rest will transfer all of its momentum at that angle to it
Is there a list of tricks I should know or are there any other tricks I should know?
- One mass colliding with an identical mass at rest will transfer all of its momentum at that angle to it
Is there a list of tricks I should know or are there any other tricks I should know?
