# Question: Is Gravity A Force Or Not?

## Why gravitation is not a force?

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..

## Did Einstein say gravity is not a force?

Einstein argued that gravity isn’t a force at all. He described it as a curvature of time and space caused by mass and energy. … Their math, laid down in 10 equations, explained how gravity could move around objects via a warped reality, accelerating without ever feeling any mysterious Newtonian forces.

## What is gravity made of?

They proposed that gravity is actually made of quantum particles, which they called “gravitons.” Anywhere there is gravity, there would be gravitons: on earth, in solar systems, and most importantly in the miniscule infant universe where quantum fluctuations of gravitons sprung up, bending pockets of this tiny space- …

## Where is gravity the strongest?

Arctic OceanHirt’s model pinpoints unexpected locations with more extreme differences. Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2.

## Is gravity matter Yes or no?

Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly. … The more massive something is, the more of a gravitational pull it exerts.

## Can we create gravity?

Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft’s hull that acts as centripetal force.

## Why is general relativity wrong?

Yet most researchers think general relativity is wrong. incomplete . After all, the other forces of nature are governed by quantum physics; gravity alone has stubbornly resisted a quantum description. … The fix is dark matter, particles invisible to light but endowed with gravity.

## Is gravity a force?

In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line. … This explains why all objects fall at the same rate.

## Why is gravity only an attractive force?

Why is gravity only an attractive force? Because mass is always positive. There are different notions of mass, but they’re equivalent. … The masses in Newton’s law of gravitation, F=Gm1m2r2, are gravitational masses.

## Who invented gravity?

Isaac Newton’sConsider how Isaac Newton’s discovery of gravity led to a better understanding of planetary motion. Isaac Newton’s formulation of the law of universal gravitation.

## Can time be bent?

Einstein’s theory of special relativity says that time slows down or speeds up depending on how fast you move relative to something else. … Also, under Einstein’s theory of general relativity, gravity can bend time. Picture a four-dimensional fabric called space-time.

## Why is gravity so weird?

2. Why is gravity so weird? No force is more familiar than gravity — it’s what keeps our feet on the ground, after all. And Einstein’s theory of general relativity gives a mathematical formulation for gravity, describing it as a “warping” of space.

## Why is gravity considered a force?

Gravity is viewed as a force because it is a force. A force F is something that makes objects of mass m accelerate according to F=ma. … Einstein explained this gravitational force, F=GMm/r2, as a consequence of the curved spacetime around the massive objects.

## What is the force of gravity formula?

The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.

## Is gravity a non contact force?

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. … All four known fundamental interactions are non-contact forces: Gravity, the force of attraction that exists among all bodies that have mass.
