Under which of the following conditions is the magnitude of the average velocity of a particle moving in one dimension smaller than the average speed over the time interval?
  1.A particle moves in the +x direction and then reverses the direction of its motion.
  2.A particle moves in the -x direction without reversing.
  3.There are no conditions for which this is true.
  4.A particle moves in the +x direction without reversing.

Question 2

If the average speed of a particle is greater than 0 m/s over some interval of time, which of the following is true?
  1.The instantaneous speed of the particle at some time during the interval could never have been greater than 0 m/s.
  2.The instantaneous speed of the particle at some time during the interval must have been equal to 0 m/s.
  3.The instantaneous speed of the particle at some time during the interval must have been greater than 0 m/s.
  4.The instantaneous speed of the particle at some time during the interval could never have been less than 0 m/s.
