Unformatted text preview: top of the rod. Connect the 1st and 2nd photogates (in the order the cart
passes) to the LabPro in ports DG1 and DG2 respectively. Attach the pulley to the end without the stopper. Be sure the track is level by adjusting the screw underneath
the track to avoid the associated Systematic Uncertainty. nut height screw Physics 1020 Laboratory #4 Force and Acceleration Starting with Logger Pro Click on the icon to open Logger Pro
CLICK HERE CLICK HERE You will have a Table as seen below. Each run will return Time in Gate1 and
Time in Gate2, the time the cart spends blocking photogate 1 and 2, respectively.
Times t1 and t2 are the times at which Velocity 1 and Velocity 2 occur. These
velocities are the instantaneous velocities of the cart at the middle of time interval
in each photogate, which is the same as the average velocity as the cart passes
through the photogate . Most importantly Acceleration or a is also returned. Physic...
