Entrance and Exit Slip Questions Unit 7 Central Net Force Entrance and Exit Slip Questions

Which direction does the net force (centripetal force) point for an object moving in a uniform circular motion? Towards the center!

Which of the following is true for an object traveling in a circular path at constant speed? its speed is constant, so its acceleration is zero. both its speed and velocity are constant. its speed is constant, but its velocity is changing. both its velocity and acceleration are constant. C
