The Einstein–Hilbert action (also referred to as Hilbert action ) in general relativity is the action that yields the Einstein field equations through the stationary-action principle. With the (− + + +) metric signature, the gravitational part of the action is given as See more Deriving equations of motion from an action has several advantages. First, it allows for easy unification of general relativity with other classical field theories (such as Maxwell theory), which are also formulated in terms … See more When a cosmological constant Λ is included in the Lagrangian, the action: $${\displaystyle S=\int \left[{\frac {1}{2\kappa }}(R-2\Lambda )+{\mathcal {L}}_{\mathrm {M} }\right]{\sqrt {-g}}\,\mathrm {d} ^{4}x}$$ Taking variations … See more • Misner, Charles W.; Thorne, Kip.

Classically (meaning non-quantum and non-GR) gravity is described by Newton's law of Universal Gravitation, in which gravity is certainly a force. However, General Relativity supersedes classical physics when it comes to gravity, and gravity is instead the manifestation of curved spacetime and is not a force. bradley creek yacht club

"Newton's classical theory of gravity offered no prospect of identifying any mediator of gravitational interaction. His theory assumed that gravitation acts instantaneously, regardless of distance. Kepler's observations gave strong evidence that in planetary motion angular momentum is conserved. (The mathematical proof is valid only in the case of a Euclidean geometry.) Gravity is also known as a force of attraction between two objects because of their mass. " - Gravity action
