Question

Quizplus · Accepted Answer

The pain experienced from a belly flop off of a high diving board is due to the cohesive forces of water. Cohesion is the force of attraction between molecules of the same type, and in water, this force is strong due to the hydrogen bonding between water molecules. When a person belly flops into the water, the water molecules come together and resist the movement of the person's body, causing the impact to be more forceful and painful. Painless wading into a pool occurs because the movement is slow enough to allow the water molecules to move out of the way and not resist the movement of the body.
