   • Motion
   • Forces
     • Normal and Mass
       • Normal is always perpendicular to surface
       • Mass must be measured in kg when using Newtons
       • When calculating mass and converting it into Newtons, gravity must be accounted for
     • Friction
       • Static Friction
         • Friction equals coefficient of static friction multiplied by the normal force
       • Kinetic Friction
         • Kinetic Friction equals the coefficient of kinetic friction multiplied by the normal force
     • Free Fall
       • 3 main equations
         • d=vi(t)+(1/2)at^2
         • a=(vf-vi)/t
         • vf^2= vi^2 + 2ad
       • The measure of an objects initial and final velocity, distance, time, and acceleration when falling or being thrown vertically
