To solve this question, you would typically use a graph that illustrates the relationship between potential energy (PE) and kinetic energy (KE) of a roller coaster as it moves along a track. This type of graph is often referred to as an Energy vs. Position graph or a Potential and Kinetic Energy graph. In these graphs, the y-axis usually represents the energy values (potential energy and kinetic energy), and the x-axis represents the position along the roller coaster track.
From this graph, you can analyze how potential and kinetic energy change at different points along the track and determine which statement about the energy of the roller coaster is true.
