murphypt Posted September 2, 2008 Report Share Posted September 2, 2008 If the force of gravity is greater than the buoyant force than the net force would imply a downward acceleration? Also, as with friction examples is it possible to buoyant force to equal downward force and obtain a constant velocity downward? Thanks! Link to comment Share on other sites More sharing options...
Pantaloons Posted September 2, 2008 Report Share Posted September 2, 2008 If the force of gravity is greater than the buoyant force than the net force would imply a downward acceleration? Yep! And if F(grav)<F(Buoy), then you would have upwards acceleration. Also, as with friction examples is it possible to buoyant force to equal downward force and obtain a constant velocity downward? Thanks! Yep! Also, with Fnet=0, you can also have objects stationary and suspended in the fluid. Link to comment Share on other sites More sharing options...
