The air tracks tend to move slightly when a glider rebounds from the lower bumper of the air track. How might this movement affect the results obtained in this experiment?

No effect on the results of that run.

The glider may accelerate less on the next run because it travels a shorter distance before reaching the photogate.

The distance between the photogate and the starting position of the glider might need to be remeasured before the next run.

The glider may accelerate more on the next run because it travels further the air track before reaching the photogate.
