True/False:

  1. Gravity is an example of inverse square behavior.
  2. A grindstone is rotating at constant rotational speed. There is a net torque on it.
  3. A lever multiplies a force but does not redirect it.
  4. On a rotating merry go round one child sits halfway out between the axis and the edge. Another child sits on the edge. Both kids have the same rotational speed.
  5. Angular momentum is a vector.
