If the quality for the object that moves in a circle is m, the radius of gyration (i.e. the distance of object to rotating shaft) of object is r, is made even
Fast circular motion angular speed is ω (cycle T), then
F=m ω2R=m (4 π2)/T2r ……(1)
It is directly proportional to mass of object m from formula (1) as can be seen that object makees the centripetal force of uniform circular motion, with circumference
The angular velocity omega square of motion is directly proportional, i.e. the cycle square T with uniform circular motion2It is inversely proportional, makees steady circular with object
The radius r of motion is directly proportional.We just verify the correctness of the formula (1) by testing below.
