In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag). ... The formula is:
The equation for universal gravitation thus takes the form: =, where F is the gravitational ... It is actually equal to the gravitational acceleration at that point.
A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.

g h is the gravitational acceleration at height h above sea level. R e is the Earth's mean radius. g 0 is the standard gravitational acceleration. The formula treats the Earth as a perfect sphere with a radially symmetric distribution of mass; a more accurate mathematical treatment is discussed below.
The acceleration is local acceleration of gravity g. ... Poisson's equation for Newtonian gravitational or electrostatic field potentials,
In classical mechanics, Newton's equation of motion in a gravitational field, written out in full, is: inertial mass × acceleration = gravitational mass × gravitational acceleration
The acceleration of a falling body in the absence of resistances to motion is dependent only on the gravitational field strength g (also called acceleration due to gravity). By Newton's Second Law the force F g {\displaystyle \mathbf {F_{g}} } acting on a body is given by: F g = m g . {\displaystyle \mathbf {F_{g}} =m\mathbf {g} .}
