Lab Activity • Employ motion sensor to measure a • Vary mass and angle and verify: • a = g sin(theta) (where sin(theta)=y/L) • Others do: motion example and MP website homework stuff/book problems.
Lab Setup: • Plug motion sensor in. Yellow into 1, black into 2. • Open DataStudio, click default choice, click create new activity. • Select Add Instrument, list the digital devices, select motion sensor. • Drag graph icon (lower left) to motion sensor icon. • Graph will display position vs. time • Prepare cart to be rolled. Click [start] button and toss cart gently. • Click stop. • To see v vs. t and a vs. t, left click on the position axis. Choices appear.
Motion Diagram Activity: • Measure positions note on your paper. • Make a table of position, velocity and accelerations. • Graph in Excel (all 3 on one page). Print. • Afix your paper to your graph. • Hand in next week!
