The discussion centers on the correct formula for calculating velocity, debating between V = v0 + 2at and V = v0 + at. It emphasizes that acceleration multiplied by time equals velocity, suggesting V = v0 + at is the correct representation. The conversation also touches on the integration of constant acceleration and references Galilei's formula, v² = v0² + 2ax, which is applicable for constant acceleration. The confusion stems from mixing different equations related to motion. Understanding these formulas is crucial for accurate calculations in physics.
