It appears when a rotating reference frame is used for analysing the system. It is exerted on all objects in the frame, and directed away from the axis of rotation.

To illustrate this concept, consider a particle P that is firmly sitting on a turntable, which is rotating about point O at angular velocity ω. The radius measured from point O to the location of the particle is R.

The centripetal accelerationCentripetal acceleration is the acceleration toward the cent... of the particle (a_c) with respect to ground is:  a_c = ω²r

This acceleration is pointing towards the centre O of rotation.

The friction forceIn physics, a force is any influence that causes a free body... (F_f) between the particle and turntable is holding the particle in place. This forceIn physics, a force is any influence that causes a free body... is determined by applying Newton’s Second Law in the direction of a_c.

Thus, F_f = ma_c. = m(ω²r)

where m is the mass of the particle.

Both of the forces described above can be observed in action on a passenger sitting in a car. When a car travels around a corner, the passenger’s body pushes against the outer edge of the car. This is an example of the reactive centrifugal forceCentrifugal force is the outward force on a body moving in a..., which can also be called a reaction force because it results from passive interaction with the car which actively pushes against the body.
