PE = mgh m = 5.44 kg g = 9.8 s2 h = 6 m Copyright © 2010 Ryan P. Murphy

PE = mgh m = 5.44 kg g = 9.8 s2 h = 6 m PE = (5.44) (9.8) (6) Copyright © 2010 Ryan P. Murphy

PE = mgh m = 5.44 kg g = 9.8 s2 h = 6 m PE = (5.44) (9.8) (6) PE = Copyright © 2010 Ryan P. Murphy

Discussion Question 1 What is the relationship between kinetic and potential energy during a roller coaster ride?

Discussion Question 2 Where on a roller coaster ride do you experience the most gravitational potential energy? The least?

Discussion Question 3 Would a roller coaster behave the same way no matter where it is located? Where might a roller coaster experience the most or least gravitational potential energy? http://www.csr.utexas.edu/grace/gallery/gravity/03_07_GRACE2.html

On which planet would we experience the least / most gravity? Discussion Question 4 Though gravitational variations on earth are not detectable in our day to day activities, they are far more apparent when compared to gravity experienced on the Moon or other planets. On which planet would we experience the least / most gravity?

Discussion Question 5 What other factors influence how efficiently potential energy is transformed into kinetic energy? Can you think of ways to slow down a roller coaster or allow it to maintain speed over a longer distance?

How would your weight differ when standing on the surface of the moon? Discussion Question 6 Gravitational potential energy defines the attraction experienced between two bodies. For example, when walking across the surface of planet Earth, your body is attracted to the Earth due the mass and density of the Earth. This same attraction can be translated into the weight you see when standing on a scale. How would your weight differ when standing on the surface of the moon?
