Energy Transfer – Friction (Discontinued) - ET-8770
Demonstrate frictional heating by measuring work done and increase in thermal energy.
Product Summary
Work is performed by pulling on the yellow cord wrapped around the cylinder and lifting the mass. The percentage of work done converted to thermal energy is calculated. Using a Rotary Motion Sensor and a Force Sensor, a real-time graph of power versus time can be generated by PASCO Capstone or SPARKvue software. The area under this curve is the work performed.
A 10 kOhm thermistor is used to determine the temperature of the cylinder. A PASPORT Temperature Sensor can be used to graph the temperature real-time using PASCO Capstone or SPARKvue. Temperature may also be measured using an ohm meter and the conversion chart.
The cylinders are mounted with a plastic insulating bolt and are easily removable to determine their mass.
