SUMMARY
The discussion focuses on the derivation of centripetal acceleration, specifically addressing the relationship between velocity and acceleration in circular motion. The key equations presented include \( w = \frac{2\pi}{T} \), \( v = rw = \frac{2\pi r}{T} \), and \( a = \frac{v^2}{R} \). A critical error identified is the incorrect differentiation of velocity with respect to time, as the magnitude of velocity remains constant while its direction changes continuously. The correct approach involves using vector calculus to derive acceleration, confirming that \( a = \frac{v^2}{r} \).
