Homework Help: Back and forth motion lab?

  1. Jun 6, 2010 #1
    Do any of these five objects move in similar ways? Which ones? What do they have in common?
    -Oscillating pendulum
    -dynamics cart rolling up and down an incline
    -student jumping into the air
    -mass oscillating at the end of a spring
    -ball tossed into the air

    My guess would be that they all move in similar ways?? I don't think I really understand what I'm being asked here. Any help would be awesome, thanks guys.
