A gravitational field affects everything that has energy (or mass, but mass is a form of energy). As such it affects virtually everything.
Gravitatinal force
It is the property of nature.
Because there is only gravitatinal acceleration
is gravitatinal potential energy renewable or nonrenewable
is gravitatinal potential energy renewable or nonrenewable
because gravitatinal potential energy of water is used to rotate turbines.
Of course not.It varies. Gravitatinal accelaration(g) indirectly propatinal to squared value of distance from centre of earth. g=GM/(R^2) G=universal gravitatinal constant M=mass of earth R=distance from centre
It's false that 1 field of science can't affect another field.
Tides form due to variations of gravitatinal pull between earth ,moon and sun.
Other planets
It depends upon density and radius. g=GM\[R]^2 G is the Universal Gravitatinal Constant
