Here is a force diagram of a person on the surface of the Earth and a person in the space station with "fake gravity". The person on the ground has the two forces that are equal in magnitude (thus ...

You may have heard that gravity isn't a force. This is true. Gravity is not a force; however, this truth leaves us with a number of questions. For example, we're commonly told that gravity "pulls ...

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.

If gravity is a quantum mechanical force, adjacent free-falling masses, each of which is in a superposition of being in two places at once, could get entangled by gravity such that measuring the ...

The crowning achievement of the 18th-century researcher was the design of the first experiment to measure the force of gravity between masses in a lab. Skip to main content.
