Mrs. Miller and her class were spending the day at an amusement park. Mrs. Miller pointed out that the first hill is always the
tallest and that all the other hills after that are not as tall. She asked her students why they think this might be the case. Her students stated that the roller coaster does not have enough energy for bigger hills. When Mrs. Miller asked, “Where does the energy go?Emily: The energy that the roller coaster used to go up the hill disappears, so the roller coaster only has a little energy left. Drew: The roller coaster used up all the energy that it was given from going up the first hill. Pam: Some of the energy was changed into sound and heat and couldn’t be changed into motion. Marcie: The energy was absorbed by the people in the roller coaster. Cort: The energy was lost into the air. John: The hills create less and less energy because they get smaller and smaller. which student is correct?
Pam is correct because energy is never created neither destroyed. Energy doesn't disappear, it simply is transformed into something else. In this case, some energy was transformed into sound and heat, because of that there isnt enough kinetic energy for the roller coaster to have another hill as high as the first one.
The chloroplast is found only in plant cells. it is the organelle that conducts photosynthesis, but mitochondria are known as the PowerHouse of the cell, and store energy.
