One of the most critical concepts you will cover in preparation for your MCAT is the topic of velocity, often confused with ‘speed'. Velocity questions may be disguised in any of the topics covered later on, from simple accelerate to circuits, waves and optics.
The video below gives you a quick overview of the difference between speed and velocity, followed by a detailed explanation of the velocity concept and equation manipulations.
