F m 1 m 2 2r. A law stating that any two masses attract each other with a force equal to a constant called the gravitational constant multiplied by the product of the two masses and divided by the square of the distance between them. What are the SI units of the proportionality constant G.
If the two masses are m1 and m2 and the distance between them is r the magnitude of the force F is.
The law of universal gravitation is an essential principle of physics. The gravitational force between two bodies forms an action and reaction pair. A student attempts to measure the maximum possible distance two masses can be away from one another and still register on the force-meter available. The law of universal gravitation is an essential principle of physics.
