Newtons universal law of gravitation states that Everybody in this universe attracts every another body with a force which is directly proportional to product of their masses and inversely proportional to square of the distance between their centers. If the two masses are m1 and m2 and the distance between them is r the magnitude of the force F is. Newtons place in.
You figured that three laws are enough for any scientist.
The value of G varies witha height above the earths surfaceb depth below the groundc radius of the planetd None. Newtons law of universal gravitation states that everybody of nonzero mass attracts every other object in the universe. This attractive force is called gravity. The universal gravitation equation thus takes the form.
