... The laws governing the motion of an object, as given in the previous chapters, apply only when all the forces acting on the object are taken into account. In the real world all objects move through fluids so we must include the forces exerted by the extremely large number of fluid molecules. In some ...

Momentum and Collisions
... When two objects collide, the total momentum of both objects before the collision is the same after the collision as expressed in the following equation. A, B are the two objects that collide and i and f are the initial and final momentums of the respective objects. PA,i + P B,i = P A,f + P B,f Ther ...
