Question 1007674: A 10kg mass is being twirled around in a horizontal circle on a 7m long string. The speed of the mass is 4m/s.
1. Calculate the force.
2. How is the force acting on the mass? (What direction is the force acting?)
3. What is the "f-word" that is a false concept of uniform circular motion?

1) The centripetal force is calculated as
so that
F = 10*4^2 / 7 = 160 / 7 = 22.86 N
2) Centripetal means "toward the center," and that is the direction the force is directed.
3) The centrifugal "force" is the mythical force commonly believed to be involved here.
