NASA has been using swimming pools to train astronauts since the 1960s. The largest is the Neutral Buoyancy Laboratory (NBL), which holds roughly 9 olympic pools worth of water and has contained not just mockups of space station and...

Deep in a Sardinian mine, researchers are constructing an experiment that hopes to solve what's known as The Worst Prediction In The History of Physics, and pin down the true identity of dark energy.

In 1884, the British steamer “Rumney” crashed into the French ship “Frigorifique.” Seeing their ship filling with water, the French crew climbed aboard the “Rumney.” But as they sailed towards port, a silent form emerged from the fog –...

In this episode of Crash Course Physics, Shini is very excited to start talking about Fluids. You see, she's a Fluid Dynamicist and Mechanical Engineer, so fluids are really important to her. Actually they're really important to anyone...

In this video Paul Andersen explains how contact forces result from interatomic forces. The following forces are explained at the interatomic level: normal force, applied force, friction force, tension force, spring force, and buoyant...

Mr. Andersen surveys properties of matter. A brief discussion of Archimede's Principle, Charles Law, Boyle's Law, and viscosity is included.

Join us as we investigate a classic question: what happens to the water level in a glass when a chunk of ice melts? Learn about buoyant force, density, and volume displacement, and witness the principles of physics come to life before...

Archimedes principle states that if an object is submerged in a fluid, then the buoyant force acting on it is equal to the weight of the fluid displaced by that object. Buoyant force exists because pressure increases as an object goes...

Discover the forces at work underwater, which dictate why large boats float but small pebbles sink. Physics - Forces - Learning Points. The buoyant force is an upward-acting force determined by the weight of the displaced water. Ships...

Hot air balloons rely on heat alone to keep them in the sky. How does this work? Physics - Energy And Radioactivity - Learning Points. Hot air rises in cool air because it is less dense. The hot air within a hot air balloon creates the...

We make a Cartesian diver using a drinking straw and sticky tack. When the diver is placed in a sealed bottle of water it can be controlled by squeezing and releasing the bottle, which makes it rise and fall within the water. Physics -...
