1) In circular motion,an object's speed and velocity remains constant.True or false? a) False b) True 2) What happens to an object's velocity in circular motion? a) It always changes as the object moves along the circular path b) its magnitude changes c) it remains the same d) none 3) What factors determine the force needed to maintain circular motion? a) mass,speed and radius of the circular path b) mass and speed only c) mass and radius of the circular path d) speed and radius of the circular path 4) A smaller radius of the circular path requires a smaller force to maintain circular motion at constant speed.True or false? a) True b) False 5) A satellite orbiting a planet is an example of circular motion.True or false? a) True b) false 6) The image shows the information about the UAE Mar's mission. Name the type of motion described by the satellite. a) linear motion b) circular motion 7) The speed of an object in circular motion will increase if the force is increased, provided that the mass and the radius of the circular path remain constant.True or false? a) True b) false 8) The radius of an object in circular motion will increase if the force is increased,provided the mass and speed of the object remains constant.True or false? a) True b) false 9) For an object in circular motion,an increased mass requires an increased force to keep the speed and radius constant.True or false? a) True b) false
