Dependent variables: the time it takes for the skateboarder to reach the bottom of the ramp and the final speed of the skateboarder at the bottom of the ramp. Results: Initial Height (m) Time to Reach Bottom (s) Final Speed (m/s) 0.5 2.43 4.12 1.0 3.21 6.02 1.5 3.86 7.50 2.0 4.51 8.98 2.5 5.04 10.10 3.0 5.55 11.15 3.5 6.02 12.20 4.0 6.46 13.22 Observations: The data in the table demonstrates a clear direct relationship between the initial height of the skateboarder on the ramp and their final speed at the ramp's bottom. As the initial height increases, two key trends emerge: the time taken to descend to the bottom increases, and the final speed achieved also rises. This pattern strongly supports the hypothesis that a greater initial height leads to a higher final speed. Discussion: The law of conservation of energy is one of the fundamental principles of physics that states that energy cannot be created or destroyed, only transferred or converted from one form to another. The results of this experiment are in line with this law, as we observed that the total energy of the system remained constant throughout the experiment. When a skateboarder is at the top of a ramp, they possess potential energy due to their position relative to the ground. As the skateboarder accelerates down the ramp, this potential energy is converted into kinetic energy, which is the energy of motion. This conversion of energy is an example of the law of conservation of energy in action. Our hypothesis that the initial energy of a skateboarder on a ramp is conserved and directly related to their final speed at the bottom of the ramp was supported by our results. We found that the greater the initial potential energy, the greater the final kinetic energy and resulting speed of the skateboarder. This suggests that the conservation of energy is indeed at play in this system, and that the initial potential energy of the skateboarder is being converted into kinetic energy as they move down the ramp. However, it is important to note that our results were obtained using a simulation, which may not perfectly reflect the real-world conditions of a skate park. Factors such as friction, air resistance, and the elasticity of the skateboard and ramp may all influence the transfer of energy and affect the final results. Additionally, our experiment was limited in scope, and further research may be necessary to fully understand the intricacies of energy transfer in skateboarding and other similar activities. Overall, our experiment provides strong evidence in support of the law of conservation of energy, and demonstrates the importance of this principle in understanding the physical world around us. Conclusion: The results of this experiment confirm our hypothesis that the initial height of a skateboarder on a ramp is directly proportional to their final speed at the bottom of the ramp. We observed that as the initial height increased, so did the final speed of the skateboarder. These findings support the law of conservation of energy and demonstrate the importance of understanding the principles of energy transfer and conversion in physical systems. Assignment: Energy Skate Park Testable Question: What is the relationship between the initial height of a skateboarder on a ramp and their final speed at the bottom of the ramp? Hypothesis: I predict that there is a direct and proportional relationship between the initial height of a skateboarder on a ramp and their final speed at the bottom of the ramp. Specifically, as I increase the skateboarder's initial height above the ramp's surface, the final speed achieved at the bottom of the ramp will also increase linearly. This hypothesis is based on my understanding that greater initial potential energy will result in a corresponding increase in kinetic energy and, consequently, a higher final speed as I descend the ramp.

Open the Energy Skate Park simulation and select a ramp with a range of different heights. 2. Set the skateboarder's initial height to one of the available heights. 3. Start the simulation and use the stopwatch to time how long it takes for the skateboarder to reach the bottom of the ramp. 4.
