![]() This equation describes gravitational potential energy (PE), which depends on the position of an object.The kinetic energy is proportional to the velocity squared (v 2). This energy is related to a certain mass (m) moving at a particular velocity (v). Kinetic energy (KE) is a form of energy associated with the motion of an object. ![]() This theorem states that the net work (W net) on a system is equal to the change in kinetic energy (ΔKE) of a moving object, particle, or system of objects moving together.In this equation, d is the distance the object moves while the force was exerted on it, and cosine theta (cosθ) is the angle between the force and the displaced object.ģ. This equation describes the work energy principle, or the work (W) done by a constant force (F) on an object that is moving in a specific direction.This equation is Newton’s second law, which states that the net force (F) on an object is proportional to the object’s mass (m) and acceleration (a).This content category focuses on motion and its causes, as well as various forms of energy and their interconversions. There are a lot of physics equations out there, but which ones do you actually need to know for the MCAT? Keep reading to get a look at each physics equation that the AAMC recommends you know, broken down by content category: Take a closer look at the content categories on the MCAT with the AAMC’s guide " What is on the MCAT Exam?" Essential physics equations for the MCAT Approximately 40% of the chemistry and physics section will focus on this foundational concept and will include the following physics related content categories:ĤA – Translational motion, forces, work, energy, and equilibrium in living systemsĤB – Importance of fluids for the circulation of blood, gas movement, and gas exchangeĤC – Electrochemistry and electrical circuits and their elementsĤD – How light and sound interact with matterĤE – Atoms, nuclear decay, electronic structure, and atomic chemical behavior The AAMC has identified your understanding of how complex living organisms transport materials, sense their environment, process signals, and respond to changes – in terms of physical principles – as a foundational concept on the MCAT. When to start studying for the MCAT and how to study for the MCAT will depend, in part, on how much knowledge you have retained from your introductory physics courses. You can expect to see physics related questions that are passage-based as well as a few stand-alone discrete physics questions. What do we mean by introductory physics? You will not be using overly complex physics equations on this section of the MCAT, but rather, you will need to be able to apply physics concepts from your two-semester introductory level university physics course to demonstrate a broad understanding of the dynamics within living systems. ![]() How much introductory physics is on the MCAT? According to the AAMC, you can expect approximately 25% of the questions in this section to relate to introductory physics. ![]() You may be wondering just how much physics you will see on the MCAT? Your physics knowledge will come into play within the first section of the MCAT: Chemical and Physical Foundations of Biological Systems.
