A submersible you can move around to play around with some physics. Here are some things you can take note of: -- How upthrust (a.k.a. buoyancy force) increases when more of an object is immersed in a liquid -- Whether an object floats or sinks depends on the maximum upthrust that can be provided vs. its weight -- The increase in pressure with depth -- The increase in drag with velocity -- When forces are unbalanced, the submersible accelerates (i.e. its velocity changes) -- When forces are balanced (i.e. net force = 0), acceleration is 0 and the submersible moves at constant velocity -- Even when there is initially a net force, because of drag balancing the forces, objects do not accelerate forever and reach a terminal velocity Notes: -- There are rocky peaks in the background, which are just to help you navigate the area. -- Force is measured in meganewtons (1 MN = 10^6 N) -- Light intensity vs. depth is not realistic in this simulation because I unfortunately picked a scale of 1 px = 1 m)
