What is the law of gravity simple?

Newton’s law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. …

Is gravity a theory or law?

This is a law because it describes the force but makes not attempt to explain how the force works. A theory is an explanation of a natural phenomenon. Einstein’s General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.

What are the three law of gravity?

So for Newton, the force of gravity acting between the earth and any other object is directly proportional to the mass of the earth, directly proportional to the mass of the object, and inversely proportional to the square of the distance which separates the centers of the earth and the object.

What is gravity lesson?

““Every object that has mass has gravitational pull. The amount of gravity pulling objects together depends on two things: how much mass the objects have, and how far apart the objects are. The farther away objects are from each other, the less gravitational pull there is, but it never stops working.

What is gravity and how does it work?

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

Does the gravity of an object depend on its size?

The gravity of an object depends on its size. To be more specific, the Gravity of an object depends on the mass of that object. It is undoubtedly the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. Relationship Between Gravity and Weight

What is the definition of gravity according to Einstein?

Gravity is accurately described by Einstein’s General Theory of Relativity, in which gravity is not treated as a force but a consequence of the curvature of spacetime which is caused by the uneven distribution of masses.

What is the formula for the force of gravity?

The gravitational equation says that the force of gravity is proportional to the product of the two masses (m1 and m2), and inversely proportional to the square of the distance (r) between their centers of mass. Mathematically speaking, F=Gm1m2 / r2, where G is called the Gravitational Constant.
