An elastic collision is a type of collision where both momentum and kinetic energy are conserved. This means that after two objects collide, they bounce off each other with no loss of energy to heat, sound, or deformation. Instead, the energy is transferred cleanly from one object to another. We can see a clear example of this in a well-known physics demonstration involving two suspended bowling balls. In this setup, one ball is pulled back and released. It swings forward, collides with the seco

Physics demo of both elastic and inelastic collisions in one dimension. In elastic collisions both momentum and kinetic energy are conserved. In inelastic collisions only momentum is conserved. Can you think of some real-world examples where understanding collisions like these is important? | Fadhel Mahdi
