This simulation show The relations between acceleration, velocity and displacement in simple harmonic motion{(b. investigate the motion of an oscillator using experimental and graphical methods) and (g. describe with graphical illustrations, the changes in displacement, velocity and acceleration during simple harmonic motion)}, right ? ??? Thanks

Hi rare, do the Exercises. it will help u make sense:)
Exercises:
Oscillations
Content
Simple harmonic motion

  1. Run the simulation with b = 0 (no damping) and X driver = 0 ( no driver amplitude). Explore the various sliders to make sense of the sliders. Describe the motion of these free oscillations with reference to acceleration and displacement. Describe and relate to other examples of simple free oscillations.
  2. Investigate the relationship of the displacement, velocity and acceleration versus time by exploring the Plot vs t checkbox to reveal the graphical display of the experimental view of the setup. Describe, with graphical illustrations, the changes in displacement, velocity and acceleration during simple harmonic motion.
  3. Explore the terms amplitude, period, frequency, angular frequency and phase difference in the virtual laboratory by looking for the hints in the virtual lab. Play with the sliders and make sense of these terms used commonly in SHM.
  4. Explore and record the period, T in terms of both frequency, f and angular frequency, ?. Select the 'expert' checkbox and look for the values of f and ? in relations to T.
  5. The equation a = ?2x is the defining equation of simple harmonic motion. Select the Plot vs X checkbox and record down the graph. Why is the equation is correct? Explain the negative sign and meaning of ? in terms of k and m.
  6. The equation  v = vocos? t can be used to describe the graph of v versus t (select checkbox Plot vs t and check v) Why is the equation is correct? Under what conditions is the equation valid?
  7. The equation  v = ? Math.sqrt ( xo2 - x2 )  can be used to describe the graph of v versus x (select checkbox Plot vs x and check v) Why is the equation is correct? Under what conditions is the equation valid?
  8. Explore degree of damping and the importance of critical damping by varying the slider of b. Design and record down how the values of b affects the graph of displacement vs time. Hint: The graph of energies vs time would be of interest in describing the effects of damping.
  9. Explore the amplitude and frequency of the driving force (Fdriver) and it effects on the motion of the system.
