Remember these physics principles:Newtоn’s First Lаw (“Lаw оf Inertiа”, if F = 0, then v = cоnstant).Newton’s Second Law (F = ma)Newton’s Third Law (“action=reaction”, “forces come in pairs”)Conservation of Momentum ( (mv)total initial = (mv)total final)Elastic Collisions conserve kinetic energyConservation of Angular Momentum; I1ω1 = I2ω2 Here are some useful formulae:Distance traveled (d)= (Average speed) x (time)Total displacement (d)= (Average velocity) x (time) Constant linear accelerations Constant angular accelerations vf=v0+at
