Answer 1

You can painlessly wade into a pool, but doing a belly flop off of the high diving board hurts because of the cohesion of the water molecules.

Explanation:

Water is represented as H20 where two hydrogen atoms are bonded to one oxygen atom. Due to force of attraction between the water molecules they stick together providing a greater force when an object or a body acts upon them.

Hence moving slowly in water or dipping slowly will not produce any opposite form whereas flipping does as it tries to separate the body between the water molecules when we fall with a certain amount of force.
