For an object in circular motion, the centripetal force is given by:
[tex] F=m\frac{v^2}{r} [/tex]
where
m is the mass of the object
v is the tangential speed of the object
r is the radius of the circular path
Therefore, we see from the formula that there are three physical quantities that affect the value of the centripetal force: the mass of the object, its speed and the radius of its orbit.
