How to tell if the collision is elastic or inelastic?

WebFor a collision where objects will be moving in 2 dimensions (e.g. x and y), the momentum will be conserved in each direction independently (as long as there's no external impulse in that direction). In other words, the total … WebThere is a spectrum of elasticity: collisions can range from being perfectly elastic to perfectly inelastic. As collisions become more and more inelastic, less and less kinetic energy is conserved. Perfectly Elastic Collisions In a perfectly elastic collision, the total kinetic energy of the system is conserved. lock books
