MCAT Physics Equations/Concepts questions & answers

MCAT Physics Equations/ConceptsKinematics Equations - correct answer Force of Gravity Between Two Objects - correct answer Units of G = N∗m²/kg² Kinetic Friction - correct answer Static Friction - correct answer Uniform Circular Motion - Velocity - correct answer Velocity vector is constantly changing and is tangential to the circle of motion Centripetal Acceleration - correct answer The acceleration vector always points toward the center of the circle and constantly changes direction as the object moves. Centripetal Force - correct answer Torque - correct answer θ = angle between F and the lever arm. (Max force at sin90° = 1) By convention, clockwise rotation is negative, counterclockwise rotation is positive. Work-Energy Theorem - correct answer Kinetic Energy - correct answer SI Unit for KE (all energy) = Joules = kg∗m²/s² Work - correct answer 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.
