Chapter 9 – Fluids
Flowing Fluids , such as the water flowing in the photograph at Coors Falls in Colorado, can make interesting patterns. In this Chapter , we will investigate the basic physics behind such flow. Photo credit: Digital is interesting to think about how much physics is involved in the situation shown in the photograph. First of all, there is the influence of gravity, which makes the water flow down. Second, you can see the parabolic trajectories followed by the water as it is in free-fall at a number of different locations in the photograph. Third, there is the somewhat ghostly appearance of the water.
