1. Based on the information given in the table, the skateboarder has the greatest potential energy at point A. Explain why.
In the table, it is mentioned that potential energy is directly proportional to height. Point A has the highest height among all the points mentioned in the table. Therefore, the skateboarder has the greatest potential energy at point A.
2. At which point in the image, would the skateboarder have the greatest Kinetic Energy & Why?
The skateboarder would have the greatest kinetic energy at point C.
Kinetic energy is directly proportional to velocity. As stated in the table, the skateboarder has the highest velocity at point C compared to the other points. Therefore, the skateboarder would have the greatest kinetic energy at point C.
To determine the potential energy of the skateboarder at different points, we need to consider the height of each point. At point A, the skateboarder is at the highest point of the ramp, which means they have the maximum potential energy.
Potential energy is defined as the energy possessed by an object due to its position or height relative to a reference point. In this case, the height of the skateboarder at point A is greater than at any other point on the ramp.
The higher the object is positioned, the greater its potential energy due to the force of gravity. As the skateboarder moves down the ramp, their height decreases, resulting in a decrease in potential energy.
Therefore, based on the information given in the table, the skateboarder has the greatest potential energy at point A because it is at the highest point on the ramp.
