2. Explain these apparent violations of the Conservation Laws. (a) Two asteroids of equal mass and opposite velocities strike each other head on, stick and stop moving. Does this violate Conservation of Energy? Where did their kinetic energy go? (b) A billiard ball hits the table wall and bounces off in the opposite direction. Was momentum conserved? What caused the momentum of the ball to change?

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
