The Most Common Question and Answer About Centripetal Force
Q. "If I tie a rock onto the end of a string and swing it around my head in a horizontal circle, I feel the rock pulling my arm to the outside. This certainly feels like a centrifical force and not a centripetal force. What is going on here?"
A. The pull the person swinging feels is the pull to the inside against the inertia of the object spinning. Remember, in the absence of a force, a body will travel in a straight line. In order to turn the rock, a force to the inside must be applied. According to Newton's 3rd law of motion; for every action, there is an equal and opposite reaction.
THE PASSENGER GOES TO THE OUTSIDE DUE TO THE LACK OF ENOUGH CENTRIPETAL FORCE -NOT THE APPLICATION OF A CENTRIFUGAL FORCE. This is true for anything whose motion changes from a circle to a straight line.
