If the height of the ramp is increased to start at 12 meters, the potential energy of the skateboarder at the starting point will also increase. This is because potential energy is directly proportional to height, meaning that as the height increases, the potential energy also increases.
Since potential energy is converted into kinetic energy when the skateboarder starts moving down the ramp, the increase in potential energy would result in an increase in kinetic energy as well. This implies that the skateboarder would have more kinetic energy at any given point during the investigation compared to when the ramp started at 6 meters.
So, increasing the height of the ramp to 12 meters would result in an overall increase in both potential and kinetic energy of the investigation because of the increase in potential energy at the starting point.
Energy of Skateboarder
Height Speed Potential Energy Kinetic Energy Total Energy
6m 0 m/s² 4,704 Joules 0 Joules 4,704 Joules
3m 5.4 m/s² 2,352 Joules 2,352 Joules 4,704 Joules
0m 10.8 m/s² 0 Joules 4,704 Joules 4,704 Joules
4. If we could increase the height of the ramp to start at 12 meters. How would this affect the overall Kinetic & Potential Energy of the investigation? Explain why.
