The equivalence between mass and energy in the expression E2−(pc)2 = m2c4 gives the rest mass of a particle.
Taking the condition, v = 1.0c
Relativistic Energy and Momentum
To learn to calculate energy and momentum for relativistic particles and, from the relativistic equations, to find relations between a particle's energy and its momentum through its mass.
The relativistic momentum p and energy E of a particle with mass m moving with velocity v are given by
What is the rest mass m of a particle traveling with the speed of light in the laboratory frame.
Express your answer in MeV/c2 to one decimal place.
Hint 1. Equations for momentum and energy
Compare the equations for energy and momentum if v=1.0c. What do you find when you plug these into
E2−(pc)2 = m2c4?
