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:

Gravity (the ice cream’s weight) pulls downward, and the buoyant force from the root beer pushes upward. These forces are equal and opposite, so the ice cream floats without sinking.
