Mass and Energies of Particles

%% Mass and Energies of a Relativistic Particle
% Determines the mass, rest energy, kinetic energy, and total energy of a
% particle

% Constants
c = 3.00*10^8;                  % [m/s] Speed of Light

% Inputs and Variables
Beta = input('Particle speed without c\n');
p = input('Momentum of particle in kg*m/s\n');

% Outputs and Equations
M0 = p*sqrt(1-Beta^2)/(Beta*c);
E0 = M0*c^2;
E = p*c/Beta;
K = E-E0;
