Units , vectors and Scalars MCAT prep

This document provides a comprehensive overview of various topics related to physics, specifically focusing on the concepts of units, vectors, and scalars. It begins by discussing the two common systems of units, the Imperial system, and the Metric system, with a particular emphasis on the SI base units used in science. The distinction between vectors (quantities with magnitude and direction) and scalars (quantities with magnitude only) is explained, along with practical examples. The document covers essential topics such as adding and subtracting vectors, vector multiplication, displacement, velocity, forces, acceleration, Newton's Laws, kinematic equations, air resistance, projectile motion, circular motion, mechanical equilibrium, and more. It serves as a valuable resource for understanding these fundamental concepts in physics
