The Kinetic Energy of an Electron & Proton

Click For Summary
SUMMARY

The discussion centers on the kinetic energy of an electron and a proton as they approach each other due to their mutual attraction. It is established that the kinetic energy of the electron will be less than that of the proton when they meet. This conclusion is based on the principle of conservation of momentum and the differing masses of the two particles, with the proton being significantly more massive than the electron. As they move closer, the total energy remains conserved, but the distribution of kinetic energy changes according to their masses.

PREREQUISITES
  • Understanding of Newtonian mechanics
  • Familiarity with the concepts of kinetic energy and mass

Homework Statement



A electron and proton are far way from each other. They move closer to each other due to their mutual attaction. When they meet is the kinetic energy of the eletron greater, less or even of that of the proton?

It think it's even, but I'm not sure.

What remains the same as they approach? Hint: What's conserved?
