SUMMARY
The discussion focuses on calculating the gravitational potential energy (ΔPE) of a sphere using the equation ΔPE = G × M₁ × M₂ (1/Ri - 1/Rf). The participants confirm the validity of the derived velocity equation v = 2√(GM/d) and the relationship between potential energy and kinetic energy, expressed as ΔPE = -ΔKE. The calculations provided demonstrate the total potential energy change when considering two masses, resulting in ΔPE total = -2GMm/d.
