Chapter 7. Dynamics of Systems of Particles
... We now work out two examples dealing the motion of rockets. The first one concerns a rocket in free space, whereas the second deals with vertical ascent under gravity. 7.5.1 Rocket Motion in Free Space We consider the case where a rocket is moving under the influence of no external forces. We also c ...

... For example, if someone holds down the darker ball in the collision shown above, it will not move. In that case, the momentum of the lighter ball would be transferred to the person holding the ball. The person is exerting an outside force. The law of conservation of momentum is true for objects that ...

CHAPTER 7 IMPULSE AND MOMENTUM
... energies of the objects, however, are scalar quantities that are always positive; thus, the total kinetic energy of the system of objects would necessarily be nonzero. Therefore, it is possible for a system of two or more objects to have a total kinetic energy that is not zero but a total momentum t ...
