Conversion of Energy Lab Report #5 Dr. Arora Taylur Wiggins Introduction : In this lab, you will analyze energy transfer between gravitational potential energy, kinetic energy, and energy lost due to collisions or friction (thermal energy) as a skate boarder rides along a track. 1. What type of energy does the skater have at the 2 meter mark? The skater has potential energy. 2. How high does the skater get on the other end of the ramp? On the other end, the skater on got 2 meters high. 3. Explain, in terms of the conservation of energy, why the skater will never go higher than your answer to question 2 at this point. The skater doesn’t create any more energy. When on the ramp the skater’s energy is interchanged between potential energy into kinetic energy on each side. 4. If you were to place the skater at the 5 meter mark, how high will the skater go on the other side of the track? Try it to confirm your prediction. The skater will only go 5 meters high on the other side of the track. 5. How does the skater’s kinetic energy change as he moves down the ramp? The skater’s kinetic energy increases as he moves down the ramp. 6. How does the skater’s kinetic energy change as he moves up the ramp? The skater’s kinetic energy decreases as he goes up the ramp. 7. How does the skater’s potential energy change as he moves down the ramp? The skater’s potential energy decreases as he moves down the ramp.

8. How does the skater’s potential energy change as he moves up the ramp? The skater’s potential energy increases as he moves up the ramp. 9. How does the skater’s total energy change as he moves down the ramp? The skater’s total energy stays the same as he moves down the ramp. 10. How does the skater’s total energy change as he moves up the ramp? The skater’s total energy stays the same as he moves up the ramp. 11. Describe the skater’s kinetic energy at the bottom of the ramp. The skater’s kinetic energy is the greatest whenever he is at the bottom of the ramp. 12. Describe the skater’s potential energy at the bottom of the ramp. The skater’s potential energy is the lowest at the bottom of the ramp. 13. What happens when the skater is dropped onto the ramp from above? (Hint: look at the bar graph.) If the skater is dropped onto the ramp from above the potential energy is high but as the skater goes down the potential energy converts to kinetic energy. When the skater hits the ramp the thermal energy increases. The skater then comes off the ramp and his thermal and total energy are the same. What happens to the total energy when the skater is dropped onto the ramp from above? (Again, look at the bar graph.) The total energy stays the same the whole time. Conclusion : Potential energy is the energy that is stored in an object due to its position relative to some zero position. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. Thermal energy is the energy that comes from the heated up substance. The potential energy increases as the skaters goes up the ramp because it is being interchanged from kinetic energy. Thermal energy happens when the skater is dropped onto the ramp.
