  1.yes.
  2.only if it is rotating with a constant angular speed
  3.No, a net nonzero torque would not cause an object to rotate.
  4.only if the object's angular speed changes

Question 2

Complete the following sentence: The moment of inertia of an object
  1.depends on the rotational speed of the object.
  2.will be greater for a larger-massed object than for a smaller-massed object.
