Figure (1)air track experimental device Possible Research Topics T1.Verify Newton's 1st and 2nd laws. T2.Study Uniformly accelerative motion. T3.Measure the kinetic energy of an object under uniformly accelerative movement. T4.Verify Newton's 3rd law. T5.study two-body collisions,and verify the momentum conservation law. Instruments to be used Video cameras,No.33747;Air Track,ID 33750;Rail bracket,No.33745;Camera tripod,No. 30059;Power suppler,No.667823;Air compressor with 12V power supply,No.562791; Computer based data acquisition and processing system;sliders;Wires; Hints 1.Read the experimental instructions carefully. 2.Read the manuals of the instruments to be used carefully. 3. Turn on the computer,click VIC icon to open the software;read the E-copies of the help files and air track experiment introduced. 4.Calibrate the system.You may do the following: A.Put the VIC 2L away from the rail,where L is the length of the rail. B.Use level gauge to level the VIC.Figure (1) air track experimental device Possible Research Topics T1. Verify Newton's 1st and 2nd laws. T2. Study Uniformly accelerative motion. T3.
