Provide an example describing the transformation of gravitational potential energy (GPE) to kinetic energy (KE) and back again. Describe where GPE and KE are highest and where they are lowest.
If total energy can't be created or destroyed why does a pendulum eventually stop?
Your answer should describe a situation where an object is alternating between motion and rest and how GPE and KE are changing throughout the example you describe. You may also want to mention what other factors play a role in the conversion of GPE and KE when discussing the pendulum.
