Question

which of the following best describes an elastic collision?
only energy is conserved
both momentum and kinetic energy are conserved
kinetic energy is not conserved
momentum is not conserved

Explanation:

An elastic collision is defined as a collision where two key quantities are conserved: the total momentum of the system, and the total kinetic energy of the system. In contrast, inelastic collisions conserve only momentum, not kinetic energy.

Answer:

B. Both momentum and kinetic energy are conserved
