10 questions
Part A: For the first three scenarios (questions 1-5), determine whether the object described has only potential energy (PE), only kinetic energy (KE), both PE and KE, or neither PE nor KE. Select the correct choice. A hint is provided for each question.
Part B: For the next three scenarios (questions 6-10), determine how the potential energy (PE) and/or kinetic energy (KE) of the object changes as it moves. Select the best answer. At least one hint is provided for each question.
Part C: Read the prompt for your Science Journal entry. Respond to the prompt using this class Padlet.

Science Journal Entry (Post on this class Padlet.)
A) Describe a time within the past 24 hours where you or an object within your control has had BOTH potential energy (PE) and kinetic energy (KE). Be specific, and make sure your example is different than what others have posted.
B) Comment on a classmate's example by explaining if or how the energy (PE and KE) would likely change immediately after the moment they describe in their scenario.
