8/31/2023 0 Comments Gravity gis Death Valley, so gravity would be expected to be stronger there (where you are closest to the Earth’s center). Therefore, you would expect gravity in the United States to be stronger wherever you are closest to the center of the Earth. In general, the closer the centers of two objects, the greater the force of gravity becomes. This acceleration of gravity is written as a small g and is used to describe the strength of gravity at different locations on Earth as well as on other planets. The ’force of gravity’ is often expressed in terms of the acceleration the gravitational force will give an object when the object is dropped. We feel the Earth pulling on us with a force that we call gravity. Your weight is actually just the force of gravity between your body's mass and the Earth's mass. However when one of the objects is very massive, such as the Earth, then the force of gravity becomes significant. The G in the relationship is a constant that is called the universal gravitational constant.įor everyday objects like people, cars, balls, and planes the force of gravity between any two of these objects is so tiny it is insignificant. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared. The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. What he actually did was give us an analytical interpretation of gravity, that is, describe the quantities that determine the gravitational force on an object.Īccording to Newton, any two objects have an attractive force trying to pull them together. Isaac Newton is credited with ’discovering gravity’. Of the four fundamental forces - gravity, electromagnetic, strong nuclear, and weak nuclear - gravity is the one with which people are most familiar. What is gravity and where is it the strongest in the United States? January 2003
