Thus, if the adequate centripetal force is not present, then the car can start slipping rather than taking the turn on the road.Īnother very common example is the movement of the earth around the sun. However, there will be a reduction in the frictional force if the tyres are worn or if the road in which the car is travelling is icy or even wet. This frictional force between the tyres and road helps in the providing centripetal force. Applications of Centripetal Force in Our Daily LivesĬonsider a car is travelling on a road and the car takes a turn in any direction. All the forces present in nature such as gravitational force, electrical force, frictional force, etc are centripetal forces. Consider the mass of a body m and the magnitude of the centripetal force f c,Ĭentripetal force is not something new. If the centripetal force is absent then the circular motion is not possible. This force is known as centripetal force. Therefore, we can also say that a body undergoing circular motion occurs when a force acts upon it in the direction toward the centre of the circular path or the circle. We know according to the second law of Newton, the acceleration is produced by the force in the same direction as that of the force. However, the direction continuously changes and always maintains its position towards the circle. If a particles move with a uniform speed of V on any given circular path having the radius (r), the particle will have a centripetal acceleration of magnitude (v 2/r). These two forces form the foundation of circular motion. They are the centripetal force and centrifugal force. It is very important to understand two basic forces while learning circular motion.
