What does the theory of general relativity describe?
What does the theory of general relativity describe?
What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.
Is the theory of relativity the theory of gravity?
General relativity, also known as the general theory of relativity and Einstein’s theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
How does the general theory of relativity describe gravity quizlet?
General relativity tells us that gravity arises from the curvature of spacetime and that the curvature arises from the presence of masses. This idea leads us to a view of gravity in which time runs more slowly in gravitational fields, black holes can exist in spacetime, and the universe has no center or edges.
What was Einstein’s theory of gravity?
Einstein did. He theorized that a mass can prod space plenty. It can warp it, bend it, push it, or pull it. Gravity was just a natural outcome of a mass’s existence in space (Einstein had, with his 1905 Special Theory of Relativity, added time as a fourth dimension to space, calling the result space-time.
What is general relativity quizlet?
General Relativity Theory. Einstein’s theory of gravity (accelerated motion) Especially important for fast-moving objects and very dense objects. Proposed by Einstein in 1915.
Which of the following correctly describes the relationship between Newton’s theory of gravity and general relativity quizlet?
Which of the following correctly describes the relationship between Newton’s theory of gravity and general relativity? Newton’s theory of gravity is an approximation to general relativity that works when gravity is relatively weak, but breaks down when gravity is strong.
Is gravity a force in general relativity?
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 the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines.
What is gravity as per Einstein?
How did Einstein explain gravity?
What is Albert Einstein’s theory of relativity?
The special theory of relativity, first described by Albert Einstein, was merely a statement of the realization that we were wrong distances in space and time are actually relative. They change depending on how fast you’re moving.
What did general relativity predict?
General relativity predicts gravitational waves, as does any theory of gravitation in which changes in the gravitational field propagate at a finite speed.
Which statement compares Newton’s and Einstein’s ideas on gravity?
Which statement compares Newton’s and Einstein’s ideas on gravity? C. Newton explained gravity as an attractive force between matter, while Einstein explained gravity as something caused by the curvature of space-time.
Which of the following is constant in the theory of relativity?
The key premise to special relativity is that the speed of light (called c = 186,000 miles per sec) is constant in all frames of reference, regardless of their motion.
Which of the following correctly describes the relationship between Newton’s theory of gravity and general relativity group of answer choices?
Which of the following statements best describes what is relative in the theory of relativity?
Which of the following statements best describes what is “relative” in the theory of relativity? The theory says that truth can never be established in any absolute sense. The theory says that the speed of light is relative and depends on who is measuring it.
What is the source of gravity?
Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
How are Newton’s and Einstein’s theories of gravity related?
In the 17th century Newton concluded that objects fall because they are pulled by Earth’s gravity. Einstein’s interpretation was that these objects do not fall. According to Einstein, these objects and Earth just freely move in a curved spacetime and this curvature is induced by mass and energy of these objects.
What did Einstein’s theory of gravity predict?
How did Einstein describe gravity?
According to Einstein, an object’s gravity is a curvature of space.
What is the significant relationship of mass gravity and spacetime in general theory of relativity?
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.
How does the general theory of relativity explain gravity?
The general theory of relativity (or general relativity for short) is a major building block of modern physics. It explains gravity based on the way space can ‘curve’, or, to put it more accurately, it associates the force of gravity with the changing geometry of space-time.
What is the source of gravity in physics?
In Newtonian gravity, this is the only source of gravity, however in GR energy, momentum, stress and strain also contribute to gravitational strength. Another example is the trajectory of a photon under gravity. It is arguable whether Newtonian gravity would predict light should be affected by gravity, but even if you make the calc
What is general relativity (GR)?
General relativity ( GR ), also known as the general theory of relativity or ( GTR ), is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.
