A rocket is launched and travels far from the Earth. The effect of the Earth's gravity on the motion
of the rocket is insignificant. As the rocket accelerates, its momentum increases.
Explain how the principle of the conservation of momentum applies to the accelerating rocket and
the exhaust gases.
