TeachMeFinance.com - explain Newton's law of universal gravitation Newton's law of universal gravitation The term 'Newton's law of universal gravitation' as it applies to the area of Earth observation can be defined as ' All bodies attract each other with what is called gravitational attraction. This applies to the largest stars as well as the smallest particles of matter. The force of attraction between two small bodies (or between two spherical bodies of any size) is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. In other words, the closer two bodies are to each other, the greater their mutual attraction. As a result, to stay in orbit, a satellite needs more speed in a low than a high orbit'.
