So I'm just wondering to what extent you need to memorize all the physics equations. I'm about halfway done with studying for physics and I have about 30 equations already. Do you need to know every equation, and every detail of it? Do passages provide equations at all? I'm just wondering if it's worth the time to memorize every detail of every equation.
Take any advice you get with a grain of salt.
With that said, I don't think I memorized too many physics equations. I think (atleast it worked in my case) focusing on the concepts that the equations describe should help you when you actually encounter them on the MCAT.
If you want an example, you can look at Pouiselle's Law (as described in general terms on the AAMC content list) which describes flow. If you think about the factors that effect flow in an intuitive sense, you will have the information you need to reconstruct the equation to the extent at which you need it for the MCAT.
You know intuitively that flow (Q) is based on:
1. Wider (R) pipes allow more flow
2. Greater pressure (P) difference between the pipes end causes greater flow
3. Greater viscosity (N) (think honey compared to water) would decrease flow.
4. Greater length (l) of the pipe would exacerbate the effects of the viscosity so longer pipes = lower Q.
Putting these together in this example you might get something that looks like Q=P*R/N*l
The actual equation is Q=(pi*P*R^4)/8*N*l
So as you can see, most of the variables are placed properly as a result of intuition. This will usually be enough to solve many questions on the MCAT.
What is important is that you know what would happen to flow if one of the variable changes. The added constants if required will most likely be given to you. Based on this equation you may be asked for example (just making this up), what would happen to the flow of blood in an artery if it constricts itself to half the diameter. If they're looking for an exact numerical value, in my experience they will give you the equation.
I don't know, I found great success in looking at the "big picture" rather than the minutiae. Hopefully other people can give you some of their advice based on their experience.
