Introduction Have you ever wondered why when you drop a steel nail into water it sinks like a stone, but when a well-built steel ship is in the ocean it floats, even though it weighs much more than a ...

It's a common swimming pool game: Force a buoyant ball underwater and let it go. The ball springs to the surface and jumps into the air. But, submerge the ball deeper underwater and the effect is ...

Ah, the stately hot air balloon. Not really useful for all that much except for having a grand old time floating around the skies, it's still a marvel of simple physics. Fill a giant balloon with air.

Inspired by the need to safeguard marine animals and promote sustainable solutions within marine environments, an interdisciplinary team of researchers from King Abdullah University of Science and ...

Archimedes’ principle can be stated as follows: Any body completely or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the body. Everyone has ...

Editor's Note: Julian Hunt, the lead researcher on this study, has contacted us to say the figures quoted in the original press release, as well as the research paper and subsequently this piece, are ...

Legend has it that the ancient Greek scientist Archimedes discovered the law of buoyancy in a bath and ran naked through the streets of Syracuse shouting “eureka!” – or “I have found it”. That is, the ...

A hollow plastic sphere is held below the surface of a fresh water lake by a cable anchored to the bottom of the lake. The sphere has a volume of 0.300 cubic meter, and the tension on the cable is 900 ...

3 Worksheets consisting of over 25 questions and answers related to Pascal’s, Archimedes and Bernoulli’s Principles with calculations of buoyant force and buoyancy with an additional question on the ...
