Special Relativity Quiz

Special relativity is an explanation of how speed affects mass, time, and space. It includes a way for the speed of light to define the relationship between energy and matter, as defined by the classic equation $E = mc^2$. It applies to 'special' cases, discussing huge energies, ultra-fast speeds, and astronomical distances, without the complications of gravity.

The classic equation is $E = mc^2$, where small amounts of mass (m) can be interchangeable with enormous amounts of energy (E). It explains how the speed of light defines the relationship between energy and matter.

Einstein officially added gravity to his theories in 1915, with the publication of his paper on general relativity. This resulted in the inclusion of gravity's effects in his theories, expanding the scope beyond 'special' cases.

<p>As an object approaches the speed of light, its mass becomes infinite, and so does the energy required to move it, making it impossible for any object to reach or exceed the speed of light.</p> Signup and view all the answers
