Q This assignment aligns with the following Unit Objectives: • (U48) Explain and apply the Law of Conservation of Energy (CLO1)(CLO2)(CLO3)(CLO5) • (U50) Discuss the components needed for work to occur (CLO2)(CLO3) • (U51) Define energy, kinetic energy, potential energy, and work. (CLO2)(CLO3) • (UDS) Develop a well thought out and correct response to various discussion questions (CLO2)(CLO3)(CLO5)(Goal 4) Do not start a new thread. Simply reply to my posting. Be sure to comment on at least two of your classmates' postings. 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 post your answers and replies to the discussion questions below 1. Explain how you could move an object and still do no work. 2. Explain the difference between the everyday use of the word “work” and the physical (physics related) use of the word “work”. How is energy related to work? 3. 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. 4. 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.
