Formula for the coefficient of restitution,e New velocity/Old Velocity =-e
Impulse The impulse imparted onto a body is the change on its momentum, unit is Ns( Newton Second)
impulse formula I=mv-mu
kinetic energy formula Ek=1/2mv^2
Newtons law of restitution For two bodies impinging directly their relative velocity after impact is equal to a constant (e) times their relative velocity before impact and in the opposite direction
