Use the image to answer the question. The bar graph shows energy data taken from a roller coaster at a theme park. Analyze the data and assess its validity. In 3–5 sentences, record your conclusions.

Question

Graph:
KE at bottom of 1st hill = 2,500,000
GPE at top of 2nd hill =1,500,000
KE at top of 2nd = 1,000,000

Answer 1

Based on the given data, it is valid to conclude that the initial kinetic energy at the bottom of the first hill is 2,500,000 units. As the roller coaster reaches the top of the second hill, it has converted some of its kinetic energy into gravitational potential energy, resulting in a decrease to 1,000,000 units. Additionally, it is valid to state that the gravitational potential energy at the top of the second hill is 1,500,000 units. The data seems to accurately represent the energy changes experienced by the roller coaster.
