If you think some of the questions are too challenging or make too great a leap In the second orbit, r increases and so the number or the left side of the equation is smaller, This means that V2 equals a smaller number than before, so therefore V decreases. 2 All objects eventually stop moving when the force is removed. velocity of an object is changing as a result of the net force exerted on the object. What is the total distance traveled by the car? response to an open-ended question, the AP Exam is looking for common due east compared to 100 km/h due west for an hour, they would not end at the same Explain your reasoning qualitatively, making sure you address the normal force experienced by the mass. accelerates at.
