What is Einstein’s theory of gravity kids?

What is Einstein’s theory of gravity kids?

Einstein showed mathematically that gravity is not really a force of attraction between all objects with mass, as Newton thought. Instead, gravity is a result of the warping of space-time. Einstein’s ideas have been supported by evidence and are widely accepted today.

What does Einstein’s theory of gravity explain?

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.

What is Einstein’s theory of relativity in simple terms?

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.

How did Einstein disprove gravity?

Einstein offered a different view of gravity, one that made sense of Mercury. Instead of exerting an attractive force, he reasoned that each object curves the fabric of space and time around them, forming a sort of well that other objects — and even beams of light — fall into.

What are 5 facts about gravity for kids?

Top 10 Facts About Gravity!

• In the whole universe, black holes have the biggest gravitational pull.

How do you explain gravity to students?

What are the 3 laws of Einstein?

I begin the discussion by offering the following three laws: ▸ The laws of physics are identical in all non-accelerating (that is, inertial) frames. ▸ The vacuum speed of light, c, is the same for all inertial frames. ▸ The total energy E of a body of mass m and momentum p is given by E=√m2c4+p2c2.

What is the best explanation of gravity?

Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

Has Einstein’s theory of gravity been proven?

The most precise test yet of one of Albert Einstein’s ideas about gravity has once again shown he was right. The finding means that physicists may need experiments that are even more accurate to figure out where his general theory of relativity breaks down and potential new forces and phenomena kick in.

What is the theory of relativity in one sentence?

According to the theory of general relativity, matter causes space to curve. It is posited that gravitation is not a force, as understood by Newtonian physics, but a curved field (an area of space under the influence of a force) in the space-time continuum that is actually created by the presence of mass.

What is a simple example of relativity?

A Relative Example One example of relativity is to imagine two people on a train playing ping-pong. The train is traveling at around 30 m/s north. When the ball is hit back and forth between the two players, the ball appears to the players to move north at a speed of around 2 m/s and then south at the speed of 2 m/s.

Is gravity a theory or a law?

Universal Gravity is a theory, not a fact, regarding the natural law of attraction.

How is Einstein’s theory of gravity different from Newton’s?

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 is the theory of relativity for kids?

Einstein came up with his first theory of relativity, called the theory of special relativity, in 1905. It revealed that no material object can ever travel as fast as light, which has a constant speed for all observers, no matter their motion. The speed of light is thus the “speed limit” of the universe.

What is the law of gravity for kids?

Newton’s Law of Universal Gravitation It states that every celestial body in the universe attracts every other celestial body. This attraction is due to a force (gravity) that depends on the mass of each body and on the distance between the bodies.
