According to standard physics, it should stay put indefinitely, at least until the ball or the dome is perturbed. Suddenly, it begins sliding down the dome without any external force.

Composition of Forces: Concurrent, resultant and equilibrant forces are described and used in calculations. Force vectors and trig are used to solve force problems.

A couple of commenters expressed concern over the use of centrifugal force after my rant on the use of the word force. So, what is the deal with these two terms? Are they ok to use? Are they real ...
