SUMMARY
The discussion focuses on calculating centripetal force using the formula F = (mv²)/r and analyzing the forces in the x and y directions. It emphasizes that work done by centripetal force in uniform circular motion is zero, as the force and displacement vectors are always perpendicular, making the angle θ equal to 90°. Consequently, the work equation W = F x Dcosθ results in zero work done, as cos90° equals zero. This conclusion is crucial for understanding the dynamics of circular motion.
