Thus it’s a measure of elastic collision. Coefficient of restitution definition: the ratio of the relative velocity after impact to the relative velocity before the. Moreover, if it approaches 1 both the equations will be satisfied approximately, which will contribute to the fact that kinetic energy is conserved which in turn will increase the fact that collision happens in an elastic plane. This proves that if the collision is elastic this will be equal to 1. Thus, we get an equation where the coefficient of restitution equals 1. Now, according to conservation of linear momentum, This law states that: 'in a system of colliding bodies (usually 2 bodies) the relative velocity of separation is directly proportional to the relative velocity of approach'. M_1(u_1 v_1)(u_1-v_1)=m_2(v_2 u_2)(v_2-u_2)\tag The coefficient of restitution often denoted e can be found with some notion of Newtons Experimental Law. The Coefficient of Restitution (e) tells us about the bounciness, or elasticity, of the collision. M_1u_1^2 - m_1v_1^2 = m_2v_2^2 - m_2u_2^2 Newton’s law of restitution states that when two bodies collide, the speed with which they move after the collision actually depends on the material from which they are made. In an elastic collision kinetic energy is conserved, so This cant be fully derived but a part of it can be.
