Uniform Circular Motion: A car goes around a circular curve on a horizontal road at constant speed. What is the direction of the friction force on the car due to the road? perpendicular to the curve outward O perpendicular to the curve inward O tangent to the curve in the forward direction O tangent to the curve opposite to the direction of the car's motion O There is no friction on the car because its speed is constant.

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.
