Module 8: Chapter 8: Matter and Energy Discussion
This discussion aligns with the following Module 8: Chapter 8: Matter and Energy objectives:
- Explain and apply the Law of Conservation of Energy (CLO1)(CLO2)(CLO3)(CLO5)(CLO6)
- Define energy, kinetic energy, and gravitational potential energy (CLO2)(CLO3)
- Analyze situations that involve kinetic and potential energy. (CLO2)(CLO3)
- Discuss the conservation of mass (CLO1)(CLO6)
Do not start a new thread. Simply reply to my posting.
Be sure to comment on at least two of your classmates' postings. Your response should be at least 5 sentences long. This includes responses to classmates' posts. Your replies must be more than a simple phrase like "I agree" or "I like your answers". Replies should reflect why you agree or like what has been posted. Your replies must reflect a genuine effort to engage your fellow classmates regarding the comments provided or the problem that has been solved. Please think about the questions and your peers' responses and reply thoughtfully and courteously, according to netiquette rules. Use good English grammar, correct punctuation, and complete sentences. While the posts will mostly be judged by their thoughtfulness and completeness, I reserve the right to take off points for grammatical errors, especially if they interfere with the clarity of your post.
Please post your answers and replies to the discussion questions below
- Describe the energy changes that accompany chemical and physical changes
- Explain the Law of Conservation of Energy in your own words. Give an example of a system where energy is conserved. Be sure to discuss why energy is conserved in this system.
- In a simulation on Earth, an astronaut in his space suit climbs up a vertical ladder. On the moon, the same astronaut makes the same climb. In which case does the gravitational potential energy of the astronaut change by a greater amount? Account for your answer.
- How does the conservation of mass relate to the conservation of energy? Give an example.
