If I let the gravitational potential energy at an infinite distance be zero Joules, then: Yes, the gravitational potential energy in this way would always be negative. Don't worry.

Gravitational potential energy is a way to calculate the energy stored in an object because of its position or distance above the floor (Fig 1). It is a simplistic formula that uses the patient’s ...

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 ...

The world of energy storage is undergoing a transformation, and one of the most exciting innovations is the mechanical battery. Unlike traditional batteries, which store energy chemically, mechanical ...

When energy is stored within a system, use this guide to solve how much is stored. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

It explained gravitational potential energy, and how that potential energy would transform into kinetic energy. It explained escape velocity, and allowed us to eventually figure out how to escape ...

Banner image: A pulsar ejecting a plume of energy. (Credit: NASA/HST/ASU/J. Hester et al.) Scientists have used a “galaxy-sized” space observatory to find possible hints of a unique signal from ...
