Conceptual - Momentum and Energy
Determine for each of the following statements whether it is always true or can be false.
True: Kinetic energy is conserved in an elastic collision.
False: Momentum of a system is not conserved when the mechanical energy is not conserved.
True: Two objects of same mass and moving at the same velocity have the same momentum.
True: In an elastic collision the momentum is conserved.
False: In a perfectly inelastic collision, the kinetic energy is conserved.
True: Kinetic energy is conserved in an elastic collision.
False: Momentum of a system is not conserved when the mechanical energy is not conserved.
True: Two objects of same mass and moving at the same velocity have the same momentum.
True: In an elastic collision the momentum is conserved.
False: In a perfectly inelastic collision, the kinetic energy is conserved.

True: Kinetic energy is conserved in an elastic collision.
True: Two objects of same mass and moving at the same
velocity have the same momentum.
True: Momentum of a system may be conserved even when
mechanical energy is not.
True: In a perfectly inelastic collision, some of the
kinetic energy is lost.
False: In an elastic collision the momentum is not
conserved.
