1. Lab 4: Kinetic friction is less than static friction So, you need to put less force to keep object moving with constant speed rather than the force you need to start moving

2. Spring force and Hook’s law

3. Harmonic Oscillator T

4. Safety Safety Goggles (provided by the instructor) and closed-toe shoes are absolutely required for this Lab Points will be deducted for group members who are not wearing goggles at any time after the experiments have started

5. Motion detector-CBR2 To be place under the masses (on the ground) which are oscillating ( can be recorded sends small clicks out from the speaker and listens for the echo off of nearby objects
