Who said gravity is not a force?

Albert Einstein
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.

Is gravity a force Yes or no?

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.

Why do people say gravity is a force?

Gravity is viewed as a force because it is a force. Einstein explained this gravitational force, F=GMm/r2, as a consequence of the curved spacetime around the massive objects.

What if gravity doesn’t exist?

Gravity compresses the Earth’s atmosphere; it creates air pressure- the driving force of wind. Without gravity, there would be no atmosphere or air pressure and thus, no wind, no cloud, no water, no hydrogen, no oxygen, its mean there would be no life at the Earth.

Can Earth suddenly lose gravity?

If Earth suddenly lost all of its gravity, we wouldn’t just start floating. The lack of any forceful gravitational pull would turn humans – and anything else with mass, like cars and buildings – into very fast-moving tumbleweeds.

Why is gravity not 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.

Can gravity be considered force?

Gravity can be considered a force (in fact, it is one). Since gravity uses energy to pull “down” on objects, gravity is a force.

What is the relationship between force and gravity?

The relationship between gravity and mass is analogous to the relationship between force and mass, namely Force = mass x acceleration. The force of gravity is obtained by multiplying the mass ‘m’ of an object by the gravitational acceleration associated with its environment.

Does the graviton really exist?

The graviton is said to be a massless, stable, spin-2 particle that travels at the speed of light. The graviton remains hypothetical , however, because at the moment, it’s impossible to detect. Although gravity on a planetary scale is strong, on a small scales it can be very feeble.
