What is the difference between rest mass and relativistic mass?
The word mass has two meanings in special relativity: invariant mass (also called rest mass) is an invariant quantity which is the same for all observers in all reference frames, while the relativistic mass is dependent on the velocity of the observer.
What is the relativistic mass of an electron?
Relativistic mass refers to mass of a body which change with the speed of the body as this speeds approaches close to speed of light, it increases with velocity and tends to infinity when the velocity approaches the speed of light. Relativistic Mass Formula Questions: 1) An electron has a rest mass of 9.11 x 10 -31 kg.
How did Einstein derive his equations?
Einstein made two heuristic and physically insightful steps. The first was to obtain the field equations in vacuum in a rather geometric fashion. The second step was obtaining the field equations in the presence of matter from the field equations in vacuum.
Does relativistic mass imply special relativity?
In summary, we’ve shown that the relativistic mass formula (1), combined with conservation of momentum in the Newtonian context, indeed imply special relativity, at least to the extent of implying the equivalence of mass and energy, and the Lorentz transformation relating relatively moving systems of inertial coordinates.
What does relativistic mass mean?
• RELATIVISTIC MASS (noun) Meaning: (physics) the mass of a body in motion relative to the observer: it is equal to the rest mass multiplied by a factor that is greater than 1 and that increases as the magnitude of the velocity increases.
What is the equation for calculating mass?
There are two formulas that may be used to calculate mass: mass is equal to the volume of an object multiplied by its density (m=v*d) and mass is equivalent to an object’s weight divided by the acceleration of gravity (m=w/g). The appropriate formula depends on the available variables.
What is the molar mass equation?
Formula Mass: The formula mass (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. Molar Mass: Molar mass is the mass in grams of 1 mol of substance (The number of particles in a mole is equal to 6.022 * 1023).
