What is gravity according to Einstein?
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 do Newton’s and Einstein’s view of gravity differ?
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 does Newton say about gravity?
Newton’s law of universal gravitation states that every mass attracts every other mass in the universe, and the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.
What is Earth gravity?
9.807 m/s²
Earth/Gravity
What is gravity by Brainly?
Gravity is the force of attraction exerted by the earth towards its center on a body or an object. Without regular physical activity, the body slowly loses its strength, stamina and ability to function well. The greater the weight of an object, the greater the influence of gravity upon it.
According to Newton , gravity is a force expressed mutually between two objects by the virtue of their masses(heavier the objects, more the gravity)…he considered gravity a pull. According to Einstein , gravity was a curvature in the 4-dimensional space-time fabric proportional to objects masses.
What is Newtons first law of gravity?
Newton’s law of universal gravitation. Newton’s law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
What is the force of gravity in newtons?
Gravity is measurable as a force, which means it can be described in Newtons (N). A Newton is the international standard unit of force. Force is different on other planets, stars, or the moon, but on Earth’s surface, 0.98N is equal to the downward force of gravity on 100 grams of mass.
Is gravity a theory or a law?
In 1915, Einstein published his Theory of General Relativity. It included an explanation for gravity. So, the answer to whether gravity is a law or a theory depends on what you are looking for. A statement of the apparent force between objects with mass, Newton’s Law of Universal Gravitation, is a law.
