Elastic Collision
In an elastic collision, both kinetic energy and momentum are conserved , This means that the total kinetic energy of the system remains constant before and after the collision.
Figure 1 : representation for an elastic collision between two objects involved in the collision, of mass〖 m〗_1, m_2 . Impulse and kinetic energy are defined as follows
According to the conservation of momentum and , kinetic energy for the elastic collision. If the collision occurs in one direction then (ox):
