Newtonian Physics

As long as we keep track of which direction the object is moving, just x if it's as we've learned here, we should be in good shape.

It's oh-so-easy to confuse quantities which belong in S with S'. Pictures labeling all quantities involved in each frame of reference can help.

Another trick to use is to remember the saying "moving clocks run slow". Time slows down for those moving at relativistic speeds. Length does the opposite: moving rulers contract.

Once again, pay attention to the difference between rest mass and rest energy and the relativistic versions. Think through whether a number should be higher or lower than the another to recognize when the calculations go awry.

Relativisitc Mass, Energy, and Momentum
