what is an elastic collision ? an elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision . both momentum and kinetic energy are conserved quantities in elastic collisions . suppose two similar trolleys are traveling toward each other with equal speed ... | in principle , momentum could also be conserved if two balls were to come out , each with half the original speed . however , the collisions are ( mostly ) elastic . the only way to ensure conservation of both momentum and kinetic energy is if just one ball comes out . | what formula do i use for elastic collisions ? |
