Why do Olympic divers sometimes bounce off the water when they enter it after a dive?
When Olympic divers enter the water after a dive, they sometimes bounce off the surface. This is because of the combination of their speed and the surface tension of the water.
When a diver enters the water, they are traveling at a high speed. This speed creates a force that is greater than the force of gravity pulling them down. As a result, the diver is pushed up out of the water.
The surface tension of the water also plays a role in the bounce. Surface tension is the force that holds the surface of a liquid together. When a diver enters the water, they break the surface tension. This causes the water to recoil and push the diver back up.
The combination of the diver's speed and the surface tension of the water can cause the diver to bounce off the water. The height of the bounce will depend on the diver's speed and the depth of the water.
