What is the 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...
What is the formula for special relativity? One of the most famous and well-known equations in all of human history, E = mc^2, translates to “energy is equal to mass times the speed of light squared.” In other words, wrote PBS...
How do you calculate gravity in general relativity? (This is the equivalence principle and is actually one of the starting points of the theory of general relativity.) So it still makes sense to ask what would be the acceleration of a...
What is the full equation of E mc2? E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that...
Why special theory of relativity is special? The part that makes special relativity so “special” is because these laws apply to everyone, everywhere at every time, including deep inside gravitational fields of all magnitudes. But to explain that, you need a...
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...
Is E mc2 special or general relativity? E = mc2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other. Does...
How is special relativity different from general relativity? The theory of relativity is traditionally broken into two parts, special and general relativity. Special relativity provides a framework for translating physical events and laws into forms appropriate for any inertial frame of...
What is theory of relativity explanation 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...
What math is used in general relativity? General relativity is a profound generalisation of special relativity which incorporates gravity. The mathematical description of general relativity requires the mathematical language of dif- ferential geometry which uses the notions of metric, connection and...
