It increases, because the centripetal force is directly proportional to the mass of the rotating body. It increases, because the centripetal force is inversely proportional to the mass of the rotating body. It decreases, because the centripetal force is directly proportional to the mass of the rotating body.Click to see full answer. Also to know is, what is the relationship between mass and centripetal force?Centripetal force is the product of velocity squared and mass divided by radius. Due to this, centripetal force must be proportional to the square of the velocity. Simply put, the doubling of the velocity of a swinging body requires four times the centripetal force to keep the body in circular motion.Secondly, what are the proportionality relationships between the centripetal force and the radius the mass and angular velocity? If the constant thing is its angular velocity, then centripetal force is proportional to the radius. If the thing which remains constant is the speed of the moving object, then the centripetal force is inversely proportional to the radius. Also, what is centripetal force proportional to? Centripetal Force. Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle.Is centripetal force directly proportional to frequency?That relation tells us that the centripetal force is proportional to the mass and to the radius and proportional to the square of the frequency.
