Gravitational field - Wikipedia
网页A gravitational field is used to explain gravitational phenomena, such as the gravitational force field exerted on another massive body. It has dimension of acceleration (L/T 2 ) and it is measured in units of newtons per kilogram (N/kg) or, equivalently, in meters per second squared (m/s 2 ).
Gravitational Field - Isaac Physics
网页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. For a point particle of mass M, the magnitude of the resultant gravitational field strength g, at distance r from M, is.

What is Gravity? How is Gravitational Field Measured from …
网页Gravity is the field around the Earth that can be measured by satellites. Changes in the gravity field are related to change or transportation of mass, which can provide information on ocean circulation, glacial melt, droughts or geodesy.
13.2: Gravitational Field - Physics LibreTexts
网页2021年5月19日 · 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.
7.2 Newton's Law of Universal Gravitation and Einstein's
网页Expressed in modern language, Newton’s universal law of gravitation states that every object in the universe attracts every other object with a force that is directed along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Newton's law of universal gravitation - Wikipedia
网页The gravitational field is a vector field that describes the gravitational force that would be applied on an object in any given point in space, per unit mass. It is actually equal to the gravitational acceleration at that point.

网页2022年2月20日 · We show how the gravitational force affects objects on Earth and the motion of the Universe itself. 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.
