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 is the theory of gravity in simple terms?

Definitions of theory of gravity. (physics) the theory that any two particles of matter attract one another with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

What did Einstein say about gravity?

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.

What is Einstein’s theory of relativity for dummies?

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 do you explain relativity to a child?

General relativity says that planets do the same thing to space-time. They actually bend space and time around themselves. That’s why things fall towards the ground. They’re falling towards the middle of the Earth because Earth is pulling space-time towards itself.

What are 5 facts about gravity for kids?

Top 10 Facts About Gravity!

• The Moon stays in place because of gravity. …
• Isaac Newton discovered gravity. …
• Gravity causes the tides in the sea. …
• Gravity saves our lives! …
• The larger the mass of an object, the more gravity! …
• In the whole universe, black holes have the biggest gravitational pull.

What causes gravity for dummies?

The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.

What are the 2 theories of gravity?

• GRAVITATIONAL THEORIES. Jacob D. …
• NEWTONIAN GRAVITATIONAL THEORY. …
• THE GENERAL THEORY OF RELATIVITY. …
• SCALAR TENSOR THEORIES.

Is the theory of gravity proven?

Universal Gravity is a theory, not a fact, regarding the natural law of attraction. This material should be approached with an open mind, studied carefully, and critically considered. The Universal Theory of Gravity is often taught in schools as a fact, when in fact it is not even a good theory.

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 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.

Is Einstein’s theory of gravity true?

But despite the triumph of Einstein’s theory—general relativity—physicists still wonder whether it will someday face the same fate as Newton’s law. While Einstein’s gravity has passed every test so far, nobody knows for sure that it applies everywhere, under all conditions.

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.

What is special theory of relativity in simple words?

Special relativity is an explanation of how speed affects mass, time and space. The theory includes a way for the speed of light to define the relationship between energy and matter — small amounts of mass (m) can be interchangeable with enormous amounts of energy (E), as defined by the classic equation E = mc^2.

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.

What is gravity in physics for kids?

What was Einstein’s theory?

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity.
