I'm doing a project on archimede's law of hydrostatic. Since I'm a scuba
diver, I went underwater a different depths with a object . My goal is to
try to figure out if the object's weight changes in proportion with the
depth.
These were my results:
Depth Lenght of my spring (Hook's law F: k * l
0 feet 25,2 cm
10 23,9
20 24,5
50 25,2
I understand that my object is lighter at 10 feet, but why does it get
heavier as I go further deep down ?
