In clаssicаl physics, kinetic energy is оften lоst аs heat in cоllisions. In modern physics, we have seen that kinetic energy can be turned into new particles. at rest: Consider two protons colliding with equal and opposite momenta to produce a pion: a) Show by energy conservation that each proton must have a Lorentz factor (NOTE: , ) b) What is the speed of each proton in this case? c) Would it require more or less energy to create a pion if one of the protons is initially at rest? Why?
