The defining equation of momentum is p=mv. This little equation can be considered in two ways mathematically. It is the summation of all the forces which have acted upon the object in question from the first instant whenever that was. In calculus it is the...

In the late 1890's physicists were conducting experiments with cathode ray tubes. Cathode ray tubes are sealed glass tubes that have wires embedded in them, so that electricity can be passed through the tubes. If the air is pumped out of a tube, the...
