Demonstrates basic principles of water, including surface tension, pressure, and buoyancy. It shows how water can hold more than its brim due to surface tension, how pressure increases with depth ...

For fluids in thermal equilibrium, the concept of pressure, P, is familiar as the force per unit area exerted by the fluid on its containing vessel. This primary, mechanical definition of pressure ...

But what really is pressure? Pressure and force are deeply related. You may have heard of Isaac Newton as just another of those long-haired physicists, but the basic unit of force is named in his ...

How to tell the difference between force and pressure guide for KS3 physics students aged 11-14 from BBC Bitesize.

GCSE AQA Units of measure - AQA Pressure Units of measurement let us describe and compare length, weight, area, volume, density and other values.

NASA Engineer Claims Major Discovery Of New Force In Physics, But Many Aren't Convinced The team claims to have generated 1G of thrust without any propellant. If true, it would be revolutionary.

Even low pressure, as is common in mechanical ventilation, can result in structural units on the cell surface, which are important in the transport of molecules and water, for example, no longer ...

Researchers in Australia have detected and controlled changes to the shape of a single molecule in response to an applied mechanical force. The feat could enable the development of miniaturized ...

Kinetic Theory, Atmospheric Pressure and Gas Pressure: Describe the kinetic theory and use it to describe the behavior of gases. Describe the concept of pressure and the instruments and units used ...
