Gravitational Field - Isaac Physics
The gravitational field is the gravitational force per unit mass that would be exerted on a small mass at that point. It is a vector field, and points in the direction of the force that the mass would feel.
Historically, gravity has played a central role in studies of dynamic processes in the Earth’s interior and is also important in exploration geophysics. The concept of gravity is relatively simple, high-precision measurements of the gravity field are inexpensive and quick, and spatial variations in …
13.2: Gravitational Field - Physics LibreTexts
The gravitational field at any point is equal to the gravitational force on some test mass placed at that point divided by the mass of the test mass. The dimensions of the gravitational field are length over time squared, which is the same as acceleration.
Einstein's Theory of Gravitation - Center for Astrophysics
Einstein's Theory of Gravitation. Our modern understanding of gravity comes from Albert Einstein’s theory of general relativity, which stands as one of the best-tested theories in science.

Visualizing Gravity: the Gravitational Field - University of Virginia
Visualizing Gravity: the Gravitational Field. Michael Fowler Introduction. Let’s begin with the definition of gravitational field: The gravitational field at any point P in space is defined as the gravitational force felt by a tiny unit mass placed at P.

2020年12月30日 · The gravitational field at any point P in space is defined as the gravitational force felt by a tiny unit mass placed at P.
13: Gravitation - Physics LibreTexts
Gravity is the first force to be postulated as an action-at-a-distance force, that is, objects exert a gravitational force on one another without physical contact and that force falls to zero only at an infinite distance.
Universal Gravitation - The Physics Hypertextbook
Every object in the universe attracts every other object in the universe with a gravitational force. The magnitude of the gravitational force between two objects is… directly proportional to the product of their masses and; inversely proportional to …
Gravitational Field -- from Eric Weisstein's World of Physics
A gravitational field is the force field created around massive bodies that causes attraction of other massive bodies. The gravitational acceleration for a particle of mass m feeling a gravitational force F is given by. (1)
