Elastic Collision

⚡ Quick Summary
An elastic collision is one where kinetic energy is conserved.
Conservation of Kinetic Energy: 1/2 * m1 * v1i^2 + 1/2 * m2 * v2i^2 = 1/2 * m1 * v1f^2 + 1/2 * m2 * v2f^2
In a perfectly elastic collision, both momentum and kinetic energy are conserved. If a ball falls on an inclined plane and makes a perfectly elastic collision, the angle of incidence equals the angle of reflection.
