This is a “how to guide” for making introductory calculations in classical physics for undergraduates studying the subject. The calculations are performed in Mathematica, and stress graphical visualization, units, and numerical answers.The techniques show the student how to learn the physics without being hung up on the math.There is a continuing movement to introduce more advanced computational methods into lower-level physics courses.Mathematica is a unique tool in that code is written as "human readable" much like one writes a traditional equation on the board.
