Why is gravity not considered 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. In the same way, the straight path of an object is bent when space and time is bent.
Is it true that gravity is a force of attraction?
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 is gravity called 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.
Is gravity a force or acceleration?
Gravity is a force that causes acceleration. It is measured by the force that it applies per kg of matter. On earth, 9.8 Newtons of force are applied to each kilogram of mass. This causes objects to accelerate at 9.8ms^-2 towards the earth.
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.
Can gravity be considered a force CER?
Gravity is not a force because it can’t move objects. Gravity is a force because a force is a push or a pull. The moon has less gravity than the Earth because it has less mass than the Earth.
Who said gravity 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.
Why gravity is not a force Quora?
This means that gravity itself is not a real force that acts on objects, because objects in free fall or just following the straightest possible path for them in curved space-time.
Is gravity a force or non-force?
According to general relativity, gravity is not a force, however it is referred as one of the four fundamental forces. This seems like a contradiction. Classically (meaning non-quantum and non-GR) gravity is described by Newton’s law of Universal Gravitation, in which gravity is certainly a force.
Is gravity a force or a curvature?
Gravity is a force. Einstein showed that gravity can be thought of as a curvature in space-time. Hence, gravitational interaction may be more appropriate for gravitational phenomena between masses.
How do we know gravity is acting on an object?
We can rewrite things slightly, to relate its position in space to its position in time. Then, when we look at this trajectory, it appears that the object is accelerating towards the earth, giving rise to the idea that gravity is acting as a force.
Is gravity the force acting on an object moving towards Earth?
Then, when we look at this trajectory, it appears that the object is accelerating towards the earth, giving rise to the idea that gravity is acting as a force. What is really happening, however, is that the object’s motion in our coordinate system is described by the geodesic equation.
