# Growth Functions

Chapter

## Abstract

If you drop a ball from a given height, its velocity will increase at a constant rate called the acceleration of gravity:
Integrating, we find that
Since \(v = gt,\tfrac{{dh}}{{dt}} = - gt\), and \(h = {{h}_{0}} - \tfrac{1}{2}g{{t}^{2}}\) where

$$\frac{{dv}}{{dt}} = g.$$

(17-1)

*v*=*gt*, assuming that at time*t*= 0, the moment at which the ball was dropped, the ball had zero velocity. Actually the velocity is itself the rate at which the altitude of the ball decreases:$$v = - \frac{{dh}}{{dt}}$$

*h*_{0}is the initial height from which the ball was dropped at time*t*= 0.## Keywords
