An empty floating boat interacts gravitationally with the earth. A different interaction with something else keeps the boat from responding to the gravitational interaction by sinking.
-What type of interaction is involved?

Question

Quizplus · Accepted Answer

The interaction that keeps the boat from sinking due to gravity is a compression interaction. This occurs between the boat and the water. The water exerts an upward force on the boat, known as buoyancy, which counteracts the force of gravity, preventing the boat from sinking. This is a result of the water being compressed under the weight of the boat and pushing back against the boat.
