7-2 Conservation of Momentum
... For each object, F = (mass) (a) = (mass) (v / t) = (mass v)/ t = p / t. Since the force applied and the contact time is the same for each mass, they each undergo the same change in momentum, but in opposite directions. The result is that even though the momenta of the individual objects changes, ...

Some of the other important results from observations of molecular clouds are reviewed in §2.3 and §2.4. It is natural to ask if other galaxies are like our own. Unf ...

Quantum-mechanical aspects of magnetic resonance imaging
