If v1 and v2 are the initial velocities of two bodies making direct collision and if u1 and u2 are their respective velocities after collision then the coefficient of restitution is given by:
1
\(\frac{{\left( {{u_1} - {u_2}} \right)}}{{\left( {{v_2} - {v_1}} \right)}}\)
2
\(\frac{{\left( {{u_1} - {u_2}} \right)}}{{\left( {{v_1} - {v_2}} \right)}}\)
3
\(\frac{{\left( {{u_1} + {u_2}} \right)}}{{\left( {{v_1} + {v_2}} \right)}}\)
4
\(\frac{{\left( {{v_1} - {v_2}} \right)}}{{\left( {{u_1} - {u_2}} \right)}}\)
