Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid(gas or liquid) at rest is acted upon by an upward, or buoyant, force the magnitude of which is equal to the weight of the fluid displaced by the body.

There are many things in our day-to day life in which we can appreciate Archimedes discovery of buoyancy:-

● It keeps all very heavy sea craft and ships afloat to bring all your comforts from overseas across the oceans.

● It helps you to float when you go to swim and it is also used in lifejackets.

● IN the past it helped airships to fly.

● It helps to make float glass so beautifully flat .

● It helps the solids to go down the drainpipes away from our homes and so we keep healthy.

● It helps to release gas in our stomach and take the bubbles out of fizzy lemonade.

● It helps the clothes in the washing machines not to accumulate at the bottom, and to become lighter and so they circle around in the water much easier to get clean.

● Buoyancy can help to make oil water separators.

● It helps to make the winds and the weather as hot air rises due to its buoyancy but can turn into a tornado if it cools down.
