 A student attempts to balance a meterstick which has a mass attached near one end. Is it easier to balance the stick with the attached mass near the top or the bottom? (534 kB) Eight cupcake cups with attached paper clip masses are observed falling in air. The effect of air resistance is apparent. All necessary data is included for quantitative analysis. (39 kB) Velocity-time graphs generated from MBL sonic ranger data are displayed for the eight cupcake cups observed in “Cups/Clips: Falling”. May be used for quantitative analysis. (39 kB) Two balls with identical initial velocities race on flexible tracks. One of the tracks is nearly level while the other dips, stays low for a distance, then rises back to the finish. Which ball reaches the far end of the track first? (34 kB) A ball dropped from rest leaves a trail of strobe images as it falls. All necessary data is included for quantitative analysis. (18 kB) A ball tossed nearly straight up leaves a trail of strobe images as it rises and falls. All necessary data is included for quantitative analysis. (20kB) A ball tossed out at an angle leaves a trail of strobe images along a parabolic path. All necessary data is included for quantitative analysis. (26 kB) A mass on a spring undergoes simple harmonic motion along a vertical axis. The motion creates a trail of strobe images which scroll horizontally to generate a position-time graph. All necessary data are included for quantitative analysis. (199 kB) A simple pendulum attached to a spring scale swings with an amplitude of 37 degrees. The scale shows that the tension in the cord varies with angle. All necessary data are included for quantitative analysis. (50 kB)
