using a puley for analysis on an air track?
I'm doing an experiment using an air track, and my school only has one photogate/lightgate. So I'm trying to figure out a way of using the pulley (not an actual pulley, one that is used with a data logger to record time and velocity) without it effecting the experiment...We have tried heaps of different ways but all the things we have done have either added too much drag to the air track trolley thing so it hasn't been able to move freely or the wire of the pulley has interfered (as it's connected to the data logger) and it has pulled the trolley down the track...so I'm stuck...Anyone got any ideas?? Or know of any other way we can measure the trolleys?
(by the way, my experiment is to do with collisions (momentum and energy))
