... When an object is in motion, we think velocity. However, we must not forget Momentum – which is also acting on the object. Momentum = a quantity defined as the product of an object’s mass and its velocity. - In a formula, P = momentum. - momentum moves in the same direction as the velocity ...

... Since the only external force acting on the system is gravity, the center of mass continues on its parabolic path as if there had been no explosion. The cm lands at R, where R is the range. The first fragment lands at 0.5R. The other fragment of equal mass must land at 1.5R. What if the fragment wer ...
