Angular velocityis a measure of the rate of change of the angular position of an object in circular motion. It is defined as the rate at which the object moves around the circumference of the circle, and is typically measured in units of radians per second (rad/s) or degrees per second (deg/s).Centripetal forceis the force that is required to keep an object moving in a circular path. It is directed toward the center of the circle, and is equal to the product of the mass of the object, the square of its angular velocity, and the radius of the circle. Centripetal force is necessary to maintain the circular motion of an object, and is typically provided by a force such as tension or friction.Centrifugal forceis the apparent force that is felt by an object moving in a circular path. It is directed away from the center of the circle, and is equal to the product of the mass of the object, the square of its angular velocity, and the radius of the circle. Centrifugal force is not a real force, but is instead an apparent force that is felt by an object moving in a circular path due to the inertia of the object. It is often confused with centripetal force, but the two forces are actually opposite in direction.
