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.
