![]() ![]() PE = mgh is the equation for gravitational potential energy (choice A is incorrect). PV = nRT is the ideal gas law (choice C is correct). ![]() V = IR is Ohm’s Law for circuits (choice D is incorrect).Ģ. PV = nRT is the ideal gas law (choice C is incorrect). Newton’s second law states that force is equal to mass multiple by acceleration (choice B is correct). Given the same wire resistance and length of a metal tube, which of the following cross-sectional areas would provide the greatest resistivity?Īnswer key for MCAT Physics Equations practice questionsġ. Which of the following best describes the effect of a decreasing resistance on current, given a constant voltage?ĥ. Over time, the resistance of the resistor decreases. A researcher sets up a simple series circuit with a single resistor. Which of the following best describes the second law of thermodynamics?Ī) Objects in motion tend to stay in motionĭ) The entropy of a perfect crystal at absolute zero is equal to zeroĤ. Which of the following is the ideal gas law?ģ. Which of the following is the equation given by Newton’s second law?Ģ. Part 3: MCAT Physics Equations practice questionsġ. By knowing these equations (like you know functional groups or amino acids), you’ll put yourself in the best position to score well on the MCAT and increase your odds of receiving that acceptance letter from the medical school of your dreams!Ĭoulomb’s Law $$F =-\frac$$ ![]() Here, we’ll show you those important equations that you should know for any MCAT physics questions you get. Now, what is an important physics equation? An important physics equation is an equation that we’ve either seen on 1) AAMC practice materials from the MCAT Official Prep Hub or 2) the AAMC’s list of content covered on the MCAT. On the MCAT, you’re not allowed to use a calculator, so physics problems written by the test-makers at the American Association of Medical Colleges (AAMC) must be solvable using simple math, estimations, or no math at all. Not to fear-for additional help with using equations, be sure to refer to our guide on MCAT math.Īs such, it is very important for premeds studying for the MCAT to build time for learning the important physics equations into their study schedules. From long equations to complex math problems to a sea of formulas, college physics can make even the best student waver.įortunately, MCAT physics relies less on your math skills and more on your critical reasoning skills. For many premeds, physics (and organic chemistry) was one of the more difficult classes they had to take in college. ![]()
