**Relativistic mass Physics@NCKU**

Calculate relativistic momentum. Explain why the only mass it makes sense to talk about is rest mass. In classical physics, momentum is a simple product of mass and velocity. However, we saw in the last section that when special relativity is taken into account, massive objects have a speed limit... As one approaches the speed of light, however, relativistic momentum becomes infinite while Newtonian momentum continues to increases linearly. Thus, it is necessary to employ the expression for relativistic momentum when one is dealing with speeds near the speed of light.

We derived an expression for the relativistic energy using the definition of relativistic momentum, and by postulating Newton's law, and integrating free-particle motion to arrive at the kinetic energy as (gamma-1)*m*c^2, where m is the rest mass, and the gamma-factor corrects this mass as a function of the particle speed....

**Find the relativistic momentum of a proton moving at speed**

Mass in special relativity The word mass is given two meanings in special relativity : one ( rest or invariant mass , and its equivalent rest energy ) is an invariant quantity which is the same for all observers in all reference frames; the other ( relativistic mass or the equivalent total energy of the body) is dependent on the velocity of the observer. how to get visa gift card to bank account Help with relativistic momentum question (self.AskPhysics) submitted 2 years ago by pookiedownthestreet An electron with a speed of 0.915c is emitted by a supernova, where c is the speed …

where m is the relativistic mass, m o is the rest mass, u is the velocity, c is the speed of light, E is the relativistic energy, K is the relativistic kinetic energy, and p is the relativistic momentum. As it can be easily noticed, these equations give imaginary values whenever u is greater than c [3] . how to find my super fund introduce the concept of 4‐momentum in Relativistic Mechanics in order to find possible Lorentz invariants involving this new quantity. The contravariant 4‐momentum is defined as:

- Relativistic momentum approaches infinity as the velocity of an object approaches the speed of light. The relativistically correct definition of momentum as p = γ m u is sometimes taken to imply that mass varies with velocity: m var = γ m , particularly in older textbooks.
