What type of force acts on a car moving around a curve?
A). Centrifugal force
B). Cohesive force
C). Centripetal force
D). Gravitational force
Centripetal force
As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion.
