# Quick Answer: Why Is Gravity Considered A Law And Not A Theory?

## Why is gravity a scientific law?

In equations formulated by Sir Isaac Newton, the force of gravity grows with the mass of two objects and gets weaker the more distant the objects are from each other.

In general, a scientific law is the description of an observed phenomenon..

## Is gravity just a theory?

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.

## What causes gravity simple answer?

The answer is gravity: an invisible force that pulls objects toward each other. … So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

## How did Einstein explain gravity?

GETTING A GRIP ON GRAVITY Einstein’s general theory of relativity explains gravity as a distortion of space (or more precisely, spacetime) caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.

## What two factors affect gravity?

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

## What does the law of gravity mean?

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 scientific fact?

While Newton’s older law of universal gravitation is accurate in most scenarios, modern physics uses Albert Einstein’s general theory of relativity to describe gravity. Acceleration of objects to due to the gravity on Earth is around 9.8 m/s2.

## Why can’t a hypothesis be proven?

Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

## Has gravity been proven?

Scientists say they have proven the existence of gravitational waves — the ripples in space-time that stem from objects moving throughout the Universe.

## What do we not know about gravity?

And some scientists think that it is made up of particles called gravitons which travel at the speed of light. However, if we are to be honest, we do not know what gravity “is” in any fundamental way – we only know how it behaves. … Gravity is not just the attraction between objects and the Earth.

## What are the three laws of gravity?

They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. More precisely, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force does not exist.
