Describe all of the forces acting on the ice cream in the root beer float. Relate these forces to the fact that the ice cream is floating.

Answer:

There are two primary forces acting on the ice cream: gravity and buoyancy. The force of gravity pulls the ice cream downward toward the center of the Earth. The buoyant force, exerted by the root beer, pushes the ice cream upward. Because the ice cream is floating and not sinking or rising further, these two forces are balanced (equal in magnitude and opposite in direction), resulting in a net force of zero. This occurs because the ice cream is less dense than the root beer.
