In an elastic collision between two bodies, which quantity is conserved in addition to momentum?
Answer and explanation
Correct answer: B. Kinetic energy
An elastic collision conserves both momentum and total kinetic energy.
Answer: Kinetic energy.
Why not the others: Velocity of each body: velocities change in a collision. Mass of each body only: that is always true but is not the distinguishing property. Potential energy only: kinetic energy is what is conserved.
