SUMMARY
The discussion clarifies the distinction between static pressure and hydrostatic pressure in fluid mechanics. Hydrostatic pressure is defined by the equation p = ρgh, where ρ is the fluid density, g is the acceleration due to gravity, and h is the height of the fluid column, resulting in a pressure of 10000h Pascals for water. Static pressure, on the other hand, is expressed as p' = p₀ + ρgh, incorporating atmospheric pressure (p₀) and yielding a total pressure of 10000h + 10^5 Pascals. Understanding these concepts is crucial for applications in fluid dynamics and engineering.

I remembered a pretty high school problem from kinematics. But it seems it can help even undergraduates to develop their understanding of what a relative motion is.
Consider a railway circle of radius ##r##. Assume that a carriage running along this circle has a speed ##v##. See the picture. A fly ##M## flies in the opposite direction and has a speed ##u,\quad |OM|=b##. Find a speed of the fly relative to the carriage.
The obvious incorrect answer is ##u+v## while the correct answer is...
