Fg (physics)

Encyclopedia : F : FG : FGP : Fg (physics)

Fg is an abbreviation used in physics and engineering for the force exerted by gravity.

On Earth, Fg is equal to the mass of an object (in kilograms) times the acceleration caused by gravity, the constant g, which is approximately 9.8 meters per second squared. This is seen in the formula:

[F_g = m g]

In a more general context, the force of gravity between two objects is described by the formula known as the Law of universal gravitation:

[F_g = -G \frac]
