SUMMARY
The discussion focuses on calculating the change in classical velocity of an electron moving from a distance of 2 Å to 1 Å from a copper nucleus. The potential energy (PE) is calculated using the formula PE = (kq1q2)/r, leading to a change in PE of 1/2 J. This change in potential energy is equated to kinetic energy (KE), where KE = 1/2mv^2. The user seeks to solve for the change in velocity (v2 - v1) but expresses confusion regarding the calculations.
