IB Physics SL A 2 24 Centripetal Force Questions

Practise applying centripetal-force equations to orbital motion, vertical circles, loops, banked roads and rotating systems.

Exam points

Identify whether friction, tension, gravity, the normal force or another real interaction supplies the centripetal force in a stated circular-motion situation.
Apply radial force balance and F=mv²/r to calculate a speed or centripetal force in orbital, horizontal or vertical circular motion.
Analyse tension, normal force and friction in loops, pendulums, rotating systems and curved roads.
