It not only increases the time the rocket is propelled, but it also adds to the force acting against the motion of the rocket (weight), decreasing acceleration. Too little weight can also be harmful; it can make th ...

conservation of linear momentum
... If a body is at rest and it suddenly separates into fragments for internal reasons, then the principle of conservation of linear momentum will still hold because there are still no external forces that modify it. As a consequence of this principle of conservation, if a person standing on ice, for ex ...
