Which of the following is an accurate conclusion of the momentum-
energy relationship?
- Particles without mass can have momentum.
- As the velocity of a particle approaches the speed of light, its
momentum will approach infinity.
- Massless particles can only travel at the speed of light.
- All of the above are accurate conclusions of the momentum-energy
relationship.

When mass travels at near light speeds, the classic definition of
momentum (p = mv) cannot be used to approximate true momentum.
Which of the following best explains this?
- Rest mass should increase as velocity increases.
