What is mass-energy equivalency? What equation shows mass-energy equivalency?
1 answer
The mass-energy equivalence principle, also known as Einstein's mass-energy equation, states that mass and energy are interchangeable, and are different manifestations of the same underlying physical property. This principle is summarized by the equation E = mc², where E represents the energy equivalent to a mass with m, and c represents the speed of light in a vacuum, which is approximately 3 x 10^8 meters per second. This equation shows that even a small amount of mass contains a large amount of energy, and vice versa. The mass-energy equivalence principle revolutionized our understanding of physics and is a fundamental concept in theories like relativity.
