Question

Obtain an expression for centripetal force.

Answer 1

Answer:

Centripetal force is easily calculated as long as you know the mass, m, of the object; its distance, r, from the center; and the tangential velocity, v. This equation is based on the metric system; note that the centripetal force, f, is measured in Newtons. One Newton is approximately 0.225 lb.

Answer 2

Answer:

centripetal force = mv^2/r or mrw^2
