4DESCRIBING MOTION

The description of the motion of an object in terms of its position, velocity, and acceleration is called kinematics. In this chapter, we’ll give a succinct review of one-dimensional kinematics while showing how the Haskell language naturally encodes its ideas and equations. We’ll use the Haskell functions introduced in Chapter 2 and the types we introduced in Chapter 3. The equations of kinematics, being largely definitional, have an almost one-to-one correspondence with Haskell functions.
