Applications of Uniform Circular Motion

1. Car Negotiating a Corner:
   • Forces:
     • Normal Contact Force NNN: Balances the weight (mg) of the car.
     • Static Friction Force Fs​: Provides the centripetal force needed for circular motion.
   • If friction is insufficient, the car may skid.
2. Car Cornering on a Banked Road:
   • The normal force provides the centripetal force without relying on friction.
3. Aircraft Banking:
   • The vertical component of the lift force (LLL) balances the weight, while the horizontal component provides the centripetal force.
4. Planets in Orbit:
   • Planets are kept in orbit by the gravitational force between them and the body they orbit around.
5. Cornering:
   • Roads are often banked (raised towards the outside) to help vehicles maintain stability while cornering.
6. Spin Dryer:
   • The drum spins rapidly to dry clothes by forcing water out through centrifugal force.
7. Centrifuge:
   • Used for separating mixtures of liquids (e.g., separating palm oil from water) and for studying forces experienced by astronauts.
