1.	Which principle of conservation can explain the flight of a rocket?
Answer» Solution :Flight of a ROCKET can be explained by the the principle of conservation of momentum. The initial momentum of the rocket, along with its fuel, is zero. The burnt fuel is EJECTED backwards through a HOLE, with some momentum. This momentum should be cancelled by an equal and OPPOSITE momentum, so that the NET momentum is still zero. this requirement for an equal and opposite momentum is responsible for the forward motion of the rocket.
