Relativistic Energy

While length decreases between two points at high speeds, the mass of an object will increase. This has a significant effect on what the object is capable of doing. Einstein’s famous relationship for energy is: E=mc^2 This includes both the kinetic energy and rest mass energy for a particle. The kinetic energy of a high speed particle can be calculated from: KE=mc^2-m_0 c^2 The relativistic energy of particle can also be expressed in terms of its momentum in the expression E=mc^2= √(p^2 c^2+ m_0^2 c^4 ) The relativistic energy expression is what is used to calculate binding energies of nuclei and the energy yields of nuclear fission and fusion.

Atomic and Nuclear Physics: Kinetic energy of electron, momentum of proton

An electron and a proton are each accelerated through a potential difference of 10.0 million volts. a) What is the kinetic energy of the electron? What is the kinetic energy of the proton? b) Calculate the momentum (MeV/c) of the proton using classical equations. c) Calculate the momentum (MeV/c) of the proton using relati

Final parameters of proton under constant acceleration

A proton (m=1.67*10^-27kg) is being accelerated along a straight line at 3.6*10^5 m/sec ^2 in a machine. If the proton has an inital speed of 2.4*10^7 m/sec: What is the final velocity after traveling for 2 sec? What is the force acting on the proton? What is the increase in its kinectic energy?

What Kinetic Energy Must this Beam Proton Have?

In the Tevatron accelerator/storage ring at the Fermi National Accelerator Laboratory, two beams of protons travel in opposite directions each with a total energy of 1 TeV and interact. Since these beams have momenta of equal magnitude but opposite direction, they interact in their center of momentum inertial frame. Hence s2 =

Relativistic Collision

This is problem 12.34 from Griffiths' third edition of Electrodynamics: In the past, most experiments in particle physics involved stationary targets: one particle (usually a proton or an electron) was accelerated to a high energy E, and collided with a target particle at rest (Fig12.29a). Far higher relative energies are o

Momentum and Relativistic Energy

Relativistic Energy and Momentum Learning Goal: 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 and energy E of a particle with mass moving with velocity is g
