GRAVITATIONAL POTENTIAL ENERGY Calculations Name: Show all work! Include units on your answers! Date: GPE = mgh = Wh m = GPE/gh h = GPE/mg = GPE/W Gravitational Potential Energy (GPE) Joules (J) W = GPE/h Mass (m) kilograms (kg) =mg Height (h) meters (m) Weight (W) Newtons (N) g = 9.8 m/s2 = acceleration due to gravity (constant) 1. Jace is sitting on a skateboard at the top of a hill that is 21 m high. Both he and the skateboard weigh 558 N. How much gravitational potential energy does he and the skateboard have?g 2. Alina placed an IPC textbook on a shelf 3.2 m high. The textbook weighs 1.9 N. How much gravitational potential energy does the textbook have? 3. A.J.is waiting in line to ride a roller coaster that weighs 1,966 N and has a 72 m hill at the beginning of the track.
