Oct 4, 2022 at 20:00 | comment | added | Agnius Vasiliauskas | No. buoyancy force is just buoyancy force. Net force would be $F_b + mg$. Depending on situation,- body density vs water density, etc, net force can be up or down or zero (object floats). Net force is a total force of all acting forces on the body center of mass. | |
Oct 4, 2022 at 19:54 | comment | added | user1007028 | I did say 'a single force that is equivalent to the action of the forces together' which is the same as net force, so when we talk about $F_b$ of a force acting on a submerged body we can think of it as being the 'net or (resultant)' forces acting upwards? So we might call it force of buoyancy but technically speaking it's the 'net upwards forces'(or resultant). In terms of a 'force' as being a single element that acts on the body these aren't forces but their resultants? (I can think of it as the value of a single force that would have the same effect as my upthrusts) | |
