Equations and Units and Relationships, oh my!

We have been tackling topics like Kinematics, Force, Motion, Gravitation, Work and Energy. There is a lot of high yield material in the first few chapters and it can often be extremely overwhelming, especially for students who haven’t taken physics in a few years.

When it comes to the physical sciences, there are three things that can help increase your physics speed and accuracy.

1. Equations- It is absolutely essential to know the equations by heart and to be able to recall them quickly. To practice equations, memorize them in chunks. What are all of the equations that deal with energy? Know them as a group and you can pick up any of them individually when you need to solve a question. Use flashcards, friends, games and mnemonics, however it works best for you, but you 100% need to know your equations on test day.

2. Units- You have to know how to break down a Joule, a Newton a Watt or an Ohm into its separate components. Frequently, answer choices will feature different units and you can eliminate based on knowing that a Newton is kg*m/s^2 so that has to be in the correct answer choice. Units are your friends.

3. Relationships- You have no calculator on the MCAT so the plug-and-chug method that most of us used in our physics classes, is often not the correct way to most quickly answer a physics question. What are the relationships between the variables. If mass increases, what happens to momentum? Is that relationship direct or inverse? Again, this can help eliminate wrong answer choices with no calculations required increasing both speed and accuracy.

So, for those of you who are struggling with physics, remember to focus on your equations, units, and relationships. If you’re having trouble, don’t hesitate to sign up for Kaplan’s MCAT prep courses. The guaranteed path to higher test scores. Happy studying!
