momentum is "mass times speed". Since both mass and speed are "relative", how could momentum NOT be? Likewise, energy is "1/2 mass times speed squared" so it also is relative to the viewer.skoks said:I understand this but I don't understand how momentum can be relative... What is dilated mass?How can energy be relative aswell?
Mass-energy equivalence is a theory proposed by Albert Einstein in his famous equation, E=mc². It states that mass and energy are interchangeable and can be converted from one form to another.
Nuclear reactions involve the conversion of a small amount of mass into a large amount of energy, in accordance with the mass-energy equivalence equation. This is what allows nuclear power plants to generate electricity.
Mass-energy equivalence is a fundamental concept in modern physics and has been used to explain many phenomena, such as the stability of atoms, the release of energy in nuclear reactions, and the behavior of particles at high speeds.
According to the mass-energy equivalence equation, the conversion of mass into energy is only possible in theory. In reality, it is not possible to convert all of an object's mass into energy because some of it will always remain as rest mass.
The concept of mass-energy equivalence has been extensively tested and proven through experiments such as the famous nuclear reactions conducted by Ernest Rutherford and the mass defect observed in nuclear reactions. Additionally, the use of nuclear energy and atomic bombs also serve as evidence of the validity of this theory.
