PLEASE REQUEST DEMOS WELL IN ADVANCE
Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

video - Uniform Linear Acceleration - VelocityPurpose:To experimentally verify acceleration down an inclined air track is constant and approximately equal to g sin θ.Note: this is the same as demo 1C20.30 Uniform Linear Acceleration - Time. The Capstone software measures the time between gates #1 & #2 and #1 & #3, and the instantaneous velocity at gates #2 and #3 (four parameters total). Procedure:   Raise one end of air track on blocks of wood to provide an incline. Place photogates on air track so that there is 'x' distance between the starting point photogate #1 and gate #2. Place '4x' distance between the starting point photogate #1 and photogate #3. Place 1cm wide flag on air glider (cart). Position the glider at the starting point and release while at rest. The instantaneous velocity of the cart at gates #2 & #3 is automatically measured via the PASCO software. Hints:Use a 2.5cm or 5.0cm thick wood block to tilt air track.Equipment:
