Interval and Standard Experiments
Most experiments that will be conducted with the DataCollector will use Standard mode, which
involves the collection of data in a continuous series. Examples include experiments to collect data on
temperature, pressure, acceleration, and velocity.
Interval mode should be selected for experiments involving series of discrete timed events, such as
repeated trials of the Gravity Drop or Energy Car experiments.
Photogate and Smart Pulley
The photogate can be used as a sensor to measure time intervals, or in conjunction with a Smart
Pulley—found in the Dynamic Pulleys, Atwood’s Machine, Ultimate Pulleys, and Spinner
experiments—to directly measure distance, speed or acceleration.
Just select SP

or SP
2
in experiment setup to activate this function of the photogate.
Open Previous Experiments
Experiments that have not yet been downloaded and erased from the DataCollector can be accessed
by tapping the Open icon in the lower right corner of the Go! screen.
When an experiment is opened, the features are exactly the same as a live experiment, except that
the Meter window is not displayed.
