Sophia is planning on going down an 8-m water slide. Her weight is 50 N. She knows that she has gravitational potential energy (GPE) at various points on the slide. At each point, her GPE can be found by using an equation. GPE = weight × height above ground

Graph her GPE versus height every 2 m as she goes down the slide. Use height in meters above ground on the y-axis. Use GPE in Joules on the x-axis.
