PHYS 1101L Lab 7 Replacement

Document Content and Description Below

Lab 7 Replacement Due: Friday, March 20th, 11:59 PM ● Write an effective, testable hypothesis. ● To experimentally determine the relationship between the mass of an object and how far it sli... des from the bottom of a ramp. ● To experimentally determine the relationship between the angle of a ramp and how far an object slides from the bottom of a ramp. ● To confirm the experimentally determined relationship with a theoretical derivation. Outline 1. Go to the PhET simulation Ramp: Forces and Motion and click “Run Now”. You will place a crate at the top of a ramp and let it slide down. The simulation is at http://phet.colorado.edu/en/simulation/ramp-forces-and-motion. If you are downloading this on your personal computer, you will also need the Javascript environment application runner. Simply google “Java Runtime Environment” and download it before trying to run this simulation. Go to ‘Friction’ tab and set μs=0.5, μk=0.3, g=9.8m/s2 . (They will most likely be pre-set as the defaults). 2. First, you will test the relationship between the mass of an object and how far that object slides off the end of the ramp. a. Write a testable hypothesis in the form “If the mass of an object (blank), then the distance it slides from the end of a ramp will (blank) because….” If the mass of an object increases, then the distance it slides from the end of a ramp will remain the same beca [Show More]
