• isolated

• closed

• open

• no system

Energy that is exchanged with its surroundings is released as

• heat (dissipates)

• more gravitational potential energy

• more elastic potential energy

• more kinetic energy

Conservation of momentum means that the initial and final momentum in a collision are

• different

• the same/equal

• impossible to determine

• always the same as the kinetic energy
