Final answer:
The centripetal force is a force that always points towards the center of rotation and causes uniform circular motion. It can be calculated using the formula Fc = mac, where Fc is the centripetal force, m is the mass of the object, a is the centripetal acceleration, and c is the radius of the circle.
Step-by-step explanation:
The centripetal force is a force that always points towards the center of rotation and causes uniform circular motion. It is perpendicular to the linear velocity and has a magnitude given by the formula Fc = mac, where Fc is the centripetal force, m is the mass of the object, a is the centripetal acceleration, and c is the radius of the circle.
