Today I was talking about electric potential. My favorite analogy for electric potential energy is gravitational potential energy. But electric potential is something different. Electric potential ...

A new crew of potential ripples in spacetime has just debuted — emphasis on the word “potential.” By loosening the criteria for what qualifies as evidence for gravitational waves, physicists ...

Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system. This form of energy has the ...

Until now, we’ve only detected gravitational waves originating in binary systems, from the merger of black holes or neutron stars. But researchers from Northwestern University have potentially ...

In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own ...

In the UK, falls in hospital are the most commonly reported patient safety incident. Risk is multifactorial and increases with age, some medications, and conditions such as delirium and dementia.

Scientists believe that planets like Earth bob in a sea of gravitational waves that spread throughout the universe. Now, an international team has gotten closer than ever before to detecting those ...

Current attempts to probe general relativistic effects in quantum mechanics focus on precision measurements of phase shifts in matter–wave interferometry. Yet, phase shifts can always be explained as ...

Perhaps the main difference if the earth were a cube would be that students would become much more frustrated trying to calculate the gravitational field. For a uniform cube with side length L and ...
