idnetlc energy [not just the nal kinetic energy) of the skater for the two different ramps/paths. (You do not need to do a calculation to make this comparison). . The work-energy principle states that work done on an object changes its kinetic energy. The gravitational force is the only force which did work on the skater in this case. Given your answer to the previous question, compare the work done by the gravitational force for the two different ramps/paths. Conservative forces are those forwhich the amount of work done in moving an object between two point independent of the path taken. Does your answer to the previous question support the assertion that the gravitational force is a conservative force? Why or why not? Now consider the frictional force. Ramp up the slider to lots of friFL'tion. create a straight ramp with a height of 7 meters which extends from somewhere in the top left of the screen to the bottom right. Send the skater down the ramp, and record their speed at the bottom. . Create a new path which starts and ends at the same point but undulates as it slopes downwards (see the picture below). You can connect additional pieces of ramp to make this shape. [nay/5am 7m om After you've made this ramp, send the skater down the ramp, and record their speed at the bottom. Compare this speed to the speed you measured in the previous question. Compare the change in kinetic energy of the skater for the two different ramps/paths. Use the workenergy principle to compare the work done by the frictional force for the two different ramps/paths. Conservative forces are those for which the amount of work done in moving an object between two points is independent of the path taken. Does your answer to the previous question support the assertion that the frictional force is a conservative force? Why or why not? 2. Use the principle of conservation of mechanical enggy to qualitatively describe the ene_rgy transformations that take place during an oiiect's motion Now that we have knowledge of the conservative and nonconservative forces in this system, we can describe the motion of the skater using energy concepts. State the principle of conservation of mechanical energy. Under what conditions are you able to apply the principle of conservation of mechanical energy? Any conservative forces have an associated potential energy, so what forms of potential energy are present in this system? At the bottom of the screen, click the option \"Friction." On the right side of the screen. use the slider to reduce friction to none for the time being. Click and drag the skater to move them to one of the ends of the U-shaped surface and release. During the motion, what forces do work on the skater? Based on your answer to c, can you use conservation of mechanial energy to describe the motion of the skater? Why or why not? Kinetic energy is the energy of motion. Uslngthe speedometer to guide your answer, at which locations is the kinetic energy greatest? At which locations is it least? As the skater moves from the location where its kinetic energy is greatest to the location where its kinetic energy is least, where does the kinetic energy go? Click \"Bar Graph" atthe top right of the screen to show how the amount of kinetic energy and potential energy changes throughout the skater's motion. Does this graph agree with your answers to the previous two questions? In a few sentences describe the energy transformations that are taking place during the motion. I In principle, without the effects of friction, how long can this motion last
