Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

The long-range influence of gravity, despite its comparative weakness, stems from its inverse-square law, where its flux remains constant over arbitrary distances due to the compensatory increase in ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Artificial gravity is the creation of an inertial force in a spacecraft, in order to emulate the force of gravity. This concept is often seen in but is not limited to science-fiction shows like "Star ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

Dr Charles Buhler takes people through his lab in a new video. He explains more about how they developed and detected a new force from large electrostatic pressure differences. They claim this force ...

Aerodynamics explains how airplanes fly through the interplay of four fundamental forces: lift, weight, thrust, and drag.

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

So if gravity can accelerate you, as can EM or a reaction engine, etc., and all of those types of acceleration are equivalent, then all of phenomena that cause those accelerations can be considered ...
