Document Summary
When immersed in water, the body feels a buoyancy force pushing the body upward. When the buoyancy force is larger than the gravitational force pulling you down, you float. The buoyancy force is determined by the amount of water you displace and the difference between your density and water"s density. The story of archimede"s is also where we get the word eureka!". When the water you displace ways more --> upward buoyance. When you way the same as the water displaced --> you"re just going to float. If you"re more dense than water you"re going to sink if you"re less dense than water you"re going to float. The wd of fresh water is 9. 8n/litre3 and for sea water it is 10. 1n/litre3. The proportion of each type of tissue in your body determines how buoyant you are. The amount of air in your body is under your control.
