This bowling ball is floating in water. The force of gravity attracting the ball to the weights is very weak, about 2 ten millionths of a newton. Is the water impeding the ball's movement? I know the water is pushing on the ball, but each force has a counter force on the other side of the ball. So is the net force on the ball zero? It may look like the sides of the bucket are squeezing the ball, but they are not. Any ideas on what I could do to allow the feeble fraction of a newton to move the ball to the weights? Thanks in advance for any insights you offer.
If your bowling ball is floating and experiences your estimated extremely small gravitational force, it will extremely slowly move towards the weights slowed only by the viscous resistance force of the water. You can easily calculate the velocity of the ball as a function of time given the force, the mass and the frictional resistance force on the ball by the viscosity in water (Stokes Law). However, you will probably have to wait eons until a movement will be visible. And much earlier your ball will get stuck because the water has evaporated.
