Motion under Gravity in One Dimension

Abstract

In this chapter, we shall examine one-dimensional motion under gravity. By their very nature, the problems are restricted to those involving bodies moving vertically under the influence of the Earth’s gravity, with or without resistance. Nevertheless, falling raindrops, parachutists, balls and so on, and upwardly projected bullets, missiles and balls comprise a very important class of problems. Because of their limited scope, we can solve virtually all such problems by examining just five types. First, there is motion without resistance. There are then upwards and downwards motions, each under the action of two different types of resistance.
