ーこニI Figure 6.5 (Example 6.4) A car moves into the page and is round- ing a curve on a road banked at an angle 0 to the horizontal. When friction is neglected, the force that causes the centripetal acceleration and keeps the car moving in its cir- cular path is the horizontal com- ponent of the normal force.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
