Physics - The centripetal force can be friction

The centripetal force can be friction

Consider the following case of a person running in a circle:

Friction provides the centripetal force for this runner

There are three forces acting on the person:

* the person's weight

* the normal reaction from the ground, and

* sideways friction

The net force is the sum of all these - in this case it is easy: the
weight is balanced by the normal reaction, leaving the resultant equal to
the friction force (directed towards the centre of the circle).

Therefore, in this case:
