🧮 Calculation Trap
What is the work done by centripetal force on an object completing one full revolution in uniform circular motion?
A. Zero ✓
B. 2 * pi * F * r
C. F * r
D. 1/2 * m * v^2
High-Yield PM&DC Rationale
Centripetal force is always orthogonal to displacement (angle = 90°), so W = F · d · cos(90°) = 0 J.
