How do you calculate gravity from distance and time?

The force of gravity between two objects can be calculated using Newton's law of universal gravitation: F = (G * m1 * m2) / r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the two objects. Time does not directly affect the calculation of gravity, as gravity is a force that acts instantaneously between objects.
