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.
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.
If the height of the ramp is increased to 12 meters, it would have an impact on the overall kinetic and potential energy of the investigation.
The potential energy of an object at a certain height is given by the equation PE = m * g * h, where m is the mass of the object, g is the acceleration due to gravity, and h is the height. As the height increases, the potential energy also increases.
In this case, since the potential energy at 6 meters is 4,704 Joules, doubling the height to 12 meters would result in the potential energy being approximately doubled to 9,408 Joules.
On the other hand, the kinetic energy of an object is given by the equation KE = (1/2) * m * v^2, where v is the velocity of the object. Since the speed of the skateboarder is not mentioned, we cannot determine the exact value of kinetic energy at each height. However, the increase in height is not directly related to the speed of the skateboarder. Therefore, the increase in height would not directly affect the kinetic energy of the investigation.
In conclusion, increasing the height of the ramp to start at 12 meters would significantly increase the potential energy of the skateboarder, but would not have a direct impact on the kinetic energy.
