Elastic collision is a type of collision between two objects in which both kinetic energy and momentum are conserved. This means that the total energy and momentum before the collision is equal to the total energy and momentum after the collision.
In elastic collision, both kinetic energy and momentum are conserved, while in inelastic collision, only momentum is conserved. This means that inelastic collisions result in a loss of kinetic energy, while elastic collisions do not.
Energy loss during elastic collision is due to the conversion of kinetic energy into other forms of energy, such as heat or sound. This is often caused by deformation or breaking of the objects involved in the collision.
The amount of energy lost during elastic collision can be calculated using the coefficient of restitution, which is a measure of the elasticity of the objects involved. This value is typically between 0 and 1, with 1 representing a perfectly elastic collision and 0 representing a completely inelastic collision.
No, energy cannot be gained during elastic collision. Energy can only be conserved or lost, but never gained. In elastic collisions, the total energy before and after the collision remains the same, but some of the initial kinetic energy may be converted into other forms of energy.
