For each animation below, answer the following questions.

  1. What is the time interval between "strobe flashes" in the motion diagram?
  2. Describe the displacement, Dx, between the strobe flashes. (i.e. Does its magnitude remain constant, increase, or decrease as time?)
  3. Does the magnitude of Dx/Dt during each time interval remain constant, increase, or decrease?
  4. Is Dx between strobe flashes positive or negative?
  5. Is Dx/Dt between strobe flashes positive or negative?
  6. If you were to measure Dx/Dt during one time interval (call it vav1) and measure Dx/Dt during the next time interval (call it vav2), would the difference, vav2 - vav1, be positive or negative or zero?  What does this tell you about the acceleration?
