MCAT Physics Equations/Concepts with Complete Solutions Provided. (Questions and Correct Answers)

Units of G = N∗m²/kg² Correct Answer Force of Gravity Between Two Objects Correct Answer Kinetic Friction Correct Answer Static Friction Velocity vector is constantly changing and is tangential to the circle of motion Correct Answer Uniform Circular Motion - Velocity The acceleration vector always points toward the center of the circle and constantly changes direction as the object moves. Correct Answer Centripetal Acceleration Correct Answer Centripetal Force θ = angle between F and the lever arm. (Max force at sin90° = 1) By convention, clockwise rotation is negative, counterclockwise rotation is positive. Correct Answer Torque Correct Answer Work-Energy Theorem SI Unit for KE (all energy) = Joules = kg∗m²/s² Correct Answer Kinetic Energy θ = angle between F and the displacement vector. Only forces (or components of forces) that are parallel or anti-parallel to the displacement vector will do work. Max work at cos0 or cos180 = 1 or -1. Correct Answer Work Correct Answer Gravitational Potential Energy Correct Answer Conservation of Energy SI Unit for Power = Watt = J/s = Energy consumption, transfer or transformation per unit time Correct Answer Power Momentum is measured in kg∗m/s Correct Answer Momentum For elastic and inelastic collisions Correct Answer Conservation of Momentum
