Potential & Kinetic Energy Webquest
1. Go to http://www.pbslearningmedia.org/resource/hew06.sci.phys.maf.rollercoaster/energy-in-a-roller-coaster-ride/
1) What do you notice about the relationship between potential and kinetic energy and the path of the coaster?
2. Go to http://phet.colorado.edu/en/simulation/energy-skate-park
(download the energy skate park interactive and answer the following questions)
Make sure to use the graph options to guide your answers. Additionally try using different skaters (with different masses) and observe any changes. Additionally once you have done a few trials, add friction to the track by using the "Track Friction" button and increasing the coefficient of friction.
1) What happens to the total energy as the rider skates along the ramp? Why do you think this is?
2) Change some options (adjust the skater, ramp, etc). What options seem to affect kinetic energy?
3) Change some options (adjust the skater, ramp, etc). What options seem to affect potential energy?
4) What happens as you increase the friction on the ramp? How does increasing friction affect the total energy of the system? What happens to the potential and kinetic energy of the skater over time as the coefficient of friction is increased?
