Concept
Newton's Law of Restitution quantifies how much kinetic energy remains for motion in the direction of the line of impact after a collision, in relation to the initial kinetic energy. The coefficient of restitution, a value between 0 and 1, is used to describe the elasticity of the collision, with 1 being perfectly elastic and 0 being perfectly inelastic.

Concept
The Coefficient of Restitution (COR) is a dimensionless value that quantifies how much kinetic energy remains after a collision between two objects, indicating the elasticity of the collision. A COR of 1 signifies a perfectly elastic collision where no kinetic energy is lost, while a COR of 0 indicates a perfectly inelastic collision where the objects do not bounce apart and kinetic energy is maximally dissipated.
Concept
An elastic collision is a type of collision where the total kinetic energy and momentum of the system are conserved. This means that, after the collision, the objects involved rebound without any loss of energy to deformation or heat, maintaining their total kinetic energy as it was before the collision.
Concept
In an inelastic collision, kinetic energy is not conserved, although total momentum is conserved. This type of collision often results in the colliding objects sticking together or deforming, converting some kinetic energy into other forms like heat or sound.
Concept
Kinetic energy is the energy possessed by an object due to its motion, and it is directly proportional to the mass of the object and the square of its velocity. This form of energy is a fundamental concept in physics, playing a crucial role in understanding the dynamics of systems and the conservation of energy principle.
