Simple Harmonic Motion

  1. Nov 11, 2007 #1
    1. The problem statement, all variables and given/known data
    I'm given the position vs. time, velocity vs. time, acceleration vs. time, and energy vs. time graphs for a simple harmonic motion, and I want to know what would happen to those graphs if air resistance is included?

    2. Relevant equations


    3. The attempt at a solution

    I'm thinking that when air resistance is included, the amplitudes would decrease for all of these graphs. Does the damping phenomenon apply to all, or just the energy vs. time graph?

    Thank you!

    You would be correct in thinking that all graphs decrease in amplitude. What made you think it only applied to energy vs time?

    When there is not air resistance, potential energy is completely transformed into kinetic energy with each successive period. However, when air resistance is present, a fraction of the energy is lost and cannot be converted into kinetic energy.
