Day 58: Buoyant Force

We started today talking through questions about the pressure under the surface of the fluid. The problems started easy, with some simple computations. But then the questions got more conceptual. How does the pressure vary if the container isn't just a cylinder or a rectangle but has angled or curved walls? How does the pressure change if you submerge something in the water? So we ran some experiments:

We also did two problems of two objects of the same dimensions but submerged different amounts under the water level. From that, we could derive the net upwards force when submerged in a fluid—the buoyant force.
