How do I calculate the acceleration of gravity underwater?

Click For Summary
The discussion centers on calculating the acceleration of gravity underwater, with participants clarifying that gravity remains approximately 9.81 m/s² regardless of depth. The original formula presented is more about net forces, including buoyancy and drag, rather than a direct calculation of gravity. It is noted that while gravity can vary slightly with altitude and depth, these changes are minimal and often insignificant for practical calculations. The conversation emphasizes that the presence of water does not alter the fundamental value of gravitational acceleration. Understanding these principles is crucial for accurate underwater physics calculations.

which stands for?
m/s2 is meters per second per second

in imperial units, g = 32.2 ft/s2, which is feet per second per second
