# Chapter 14: Static Fluids

The study of fluids brings us to an application of Newton's Laws and Conservation of Energy that does not involve rigid bodies and point particles. Instead of mass and force we use density and pressure, but the laws do not change. We simply apply them in a different context. This chapter focuses on fluids that are static, i.e., stationary. The basic concepts allow us to understand pressure variations in fluids and objects that float (or sink) in fluids.
