Newton's Law of Universal Gravitation Physics Classroom

1. But Newton's law of universal gravitation extends gravity beyond earth. Newton's law of universal gravitation is about the universality of gravity. Newton's place in the Gravity Hall of Fame is not due to his discovery of gravity, but rather due to his discovery that gravitation is universal. ALLobjects attract each other with a force of gravitational attraction. Gravity is universal. This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. Newton's conclusion about the magnitude of gravitational forces is summarized symbolically as Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, th...

1. Imagine, if you will, substituting the light bulb in Figure 1 with an x-ray tube and applying the inverse square law to the amount of radiation exposure the patient or the x-ray technician receives. From this image, it is easy to see that if you double the distance from the source of radiation, the intensity of the radiation will become one fourth the original amount. Note that if you were to measure the intensity of the radiation at a point—say, 1 foot away from the source—your result would be 20 mR. If you were to measure the intensity of radiation at 2 feet away, your result would now be 5 mR. At 4 feet away, it would be 1.25 mR, and at 8 feet, it would measure just 0.312 mR. So in a span of only 8 feet, the intensity of radiation fell from a level of 20 mR to 0.312 mR. This tremendous reduction in radiation intensity did not require any special devices, just distance. Taking advantage of the inverse square law is a very powerful tool in radiation safety. This law would apply to...

Frequently Asked Questions

What is the inverse square law of gravity?

The inverse square law proposed by Newton suggests that the force of gravity acting between any two objects is inversely proportional to the square of the separation distance between the object's centers. Altering the separation distance (r) results in an alteration in the force of gravity acting between the objects.

What kind of phenomena obey the inverse square law?

Being strictly geometric in its origin, the inverse square law applies to diverse phenomena. Point sources of gravitational force, electric field, light, sound or radiation obey the inverse square law.

How does the law of universal gravitation work?

In today's language, the law states that every point mass attracts every other point mass by a force acting along the line intersecting the two points. The force is proportional to the product of the two masses, and inversely proportional to the square of the distance between them.

How did Isaac Newton come up with the inverse square law?

The Apple, the Moon, and the Inverse Square Law. Newton never wrote of such an event, yet it is often claimed that the notion of gravity as the cause of all heavenly motion was instigated when he was struck in the head by an apple while lying under a tree in an orchard in England.
