Gravitation and Planetary Motion Quiz

Isaac Newton's law of universal gravitation is a physical law that describes the gravitational attraction between mass and bodies.

The force of gravity is proportional to the product of the two masses

Is the universal gravitational constant the same at all places and at all times?

The equation of the Law of Universal Gravitation is stated below: F(g) = G[(m1*m2)/(r*r)] r is the separation between the objects m1 and m2 are the masses of the two objects G is the universal gravitational constant F(g) is the gravitational force The gravitational force is inversely proportional to: Check all that apply.

The law of universal gravitation states that every object in the Universe exert gravitational attraction on each other.
