Mechanical Mathematics |
In this chapter, you’ll learn how mathematics is applied to basic problems in the branch of physics known as classical mechanics. This involves the relationship among force, mass, displacement (or distance), velocity (or speed), and acceleration. Ultimately, mechanical phenomena can take the form of work, energy, or power.
WHAT IS FORCE?
Force is a measure of “push.” A cart with a heavy load begins to move steadily when it is pushed (Fig. 12-1A). If the cart has a lighter load, the same “push” will make it go much faster (Fig. 12-1B). Alternatively, greater push can move the heavier load more quickly, too (Fig. 12-1C).

At A, a heavy load moves slowly when pushed. At B, a light load is moved more quickly ...
