Understanding the Equation for High Speed Energy

Click For Summary
SUMMARY

The equation for high-speed energy is defined as KE = mc² - m₀c², where m₀ represents the rest mass of a particle, and m denotes the relativistic mass. The relativistic mass can be calculated using the formula m = m₀/(sqrt(1 - (v²/c²))). This equation encompasses both kinetic energy and rest mass energy, providing a comprehensive understanding of energy dynamics for high-speed particles. The total energy is expressed as Etot = EK + m₀c² = mc².

Im no expert but i think this is how it is!

The m0 stand for the particles rest mass (the mass you can look up in a physics book) and m stand for the relativistic mass

m=m0/(sqrt(1-(v^2/c^2)))

The total energy Etot = EK + m0*c^2 = m*c^2

Did this help?
