1. When going around a sharp turn in your car, you feel like you are being forced out of
the circle, but we learned in this chapter that you are actually experiencing a force
directed toward the center of the turn. What is causing this discrepancy? (Note: this is
a pseudo ("fake") force called the centrifugal force!)
2. When going around a vertical loop on a rollercoaster, what force(s) is(are) causing the
centripetal force which causes you to move in a circle when:
1. at the bottom of the loop?
2. at the top of the loop?
