gStudent Workbook Physics Labs with Computers, Vol. 1012-07000A Tutorial Activities: Acceleration SensorTutorial Activities – Exploration of SensorsPractice using the sensors included in the Physics Bundles for the ScienceWorkshop 500interface.• Connect the ScienceWorkshop interface to the computer, turn on the interface, and turn onthe computer.The Acceleration Sensor measuresaccelerations up to five times theacceleration due to Earth’s gravity or ±5g’s (where ‘g’ is the acceleration due togravity, or 9.8 m/s 2 ). The sensor’saccuracy is 0.01 g and the sensor’s outputranges from +5 g to –5 g depending onthe direction of the acceleration. You canalso use the software to displayacceleration in units of m/s 2 . The sensorincludes a cable for connecting to theinterface and hardware for mounting thesensor on a PASCO cart.The sensor has two built-in controlslocated on the top of the sensor:Acceleration SensorTare Button: Use the tare button to zero the sensor before making a measurement. You canuse this feature to nullify the effect of the Earth’s gravity.Sensor Response Switch: The sensor response switch has two settings – “slow” and “fast”.The ‘slow’ setting reduces errors due to high frequency vibrations. Use the ‘slow’ setting whenthe acceleration is not changing rapidly, such as on elevators, roller coasters, and in automobiles.Use the ‘fast’ setting when the acceleration is changing rapidly, such as during cart collisions.You can use the software to measure very small accelerations by setting the ‘Sensitivity’ to‘Medium (10x)’ under ‘Calibration’ in the Sensor Properties window.FASTSLOWSENSORRESPONSE- +SENSORPOSITIONTAREDIRECTION OF ACCELERATIONACCELERATIONSENSORa 5CI-6558a 5 g500 scientificPASCOInterfacescientific300PASCOANALOG CHANNELSScience W orkshop D A TA LO G G ING INSTRUCTIONSScienceWorkshopInterfaceThe sensing unit inside the sensor is oriented so that the greatest sensitivity is along the directionof the two arrows on the label.©1999 PASCO scientific A - 17
