Noah drops a rock with a density of 1.73 g/cm3 into a pond. Will the rock float or sink? Explain your answer.
The rock will sink because its density (1.73 g/cm³) is greater than the density of water (1.0 g/cm³).

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.
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.
