Click on the Energy vs. Position button to see a plot of the kinetic, potential, thermal, and total energies as a function of the skater's position. Try Bar Graph to see the same information as a bar graph. For this tutorial, you should have the Coefficient of Friction (under the Track Friction button at lower right) set to "None," which means no thermal energy is generated. You should also de-select the Thermal energy choice at bottom right from the Energy vs. Position plot. Play around with the simulation. When you are done, click on the Reset button before answering the questions. Part A Click on the Energy vs. Position button, and de-select all forms of energy except kinetic energy. Where on the track is the skater's kinetic energy the greatest? The skater's kinetic energy is Click on the Energy vs. Position button, and de-select all forms of energy except kinetic energy. Where on the track is the skater's kinetic energy the greatest? 1-at its maximum value at the lowest point of the track. 2- the same everywhere. 3- at its maximum value at the locations where the skater turns and goes back in the opposite direction.
