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.

Gravitational potential energy is one way of showing the increased risk of harm from falls from a bed with increasing height. This can be combined with popliteal height to determine the best height ...

It isn't. This form of gravitational potential energy is only valid close to the surface of the Earth (you know, normal everyday stuff close).

The gravitational potential energy store As an object is lifted, work is done against the force of gravity. The higher the object, the more energy is in the gravitational potential energy store.

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 ...

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 ...

The difference between conservative and non-conservative forces is illustrated and we work through an example problem involving gravitational potential energy and kinetic energy.

Until now, our only source of gravitational waves has been binary star systems. Researchers from Northwestern University have potentially discovered a new non-binary source of gravitational waves ...
