You can practice work, energy, and power using the following simulation:
| Click to Run |
Go to the "More Features" tab and explore the ramp without friction. Keep in mind that this simulation also takes into account frictional energy and thermal energy. Set the ramp to 5 degrees and notice what happens to the total energy when you put the filing cabinet at the top of the ramp. Is the total energy conserved? Use the guy to push the cabinet. Is he adding energy to the system?
Remember that the test is on Monday!!! Enjoy your long weekend and study for the test!!!
