how can the equation of relativistic mass, m=m_0/(1-v^2/c^2)^2, determine mass from the variable m_0?
rest mass - 'at rest' relative to what?

The concept of rest mass refers to the mass of an object when it is at rest, meaning it is not moving. This is a fundamental property of matter and is a crucial component in the mass equation. The mass equation, E=mc², shows the relationship between energy (E), mass (m), and the speed of light (c). It states that mass and energy are interchangeable, and the amount of energy an object has is equal to its mass multiplied by the speed of light squared.
The theory of relativity, proposed by Albert Einstein, explains that mass and energy are two forms of the same thing and are interchangeable. This directly affects the mass equation, as it shows that an object's rest mass is not the only factor that determines its mass. The object's speed also plays a role, as it increases with speed, the object's mass also increases.
Yes, the mass equation can be applied to all types of particles and objects, regardless of their size or composition. It is a universal equation that applies to all matter and energy in the universe.
The concept of rest mass refers to an object's mass when it is at rest, while relativistic mass takes into account an object's speed and how it affects its mass. Relativistic mass is a more comprehensive concept, as it considers the object's energy and movement, while rest mass is a more simplified concept.
Yes, the mass equation can be used to determine the energy of a particle or object. This is known as the mass-energy equivalence principle, which states that mass and energy are two forms of the same quantity. By multiplying an object's mass by the speed of light squared, we can calculate the amount of energy it contains.
