I'm measuring the average speed average speed through a photogate in a fixed point somewhere in the middle of the track. I was asked to make measurements that isolate the air flow. Other sources of error are: friction between the cart and the track, air friction, errors when measuring the...

Homework Statement I am about to do an experiment where we masure the average speed of a cart released from the top of an inclined plane that has little friction (air track). The speed measurement is done by a photo gate. This is repeated a hundred times. Homework Equations I need to come up...
