As you listen to a vinyl record, how does the speed on the needle on the record change as the album progress
Each week, you will reply to two discussion forum questions. You may submit your answers together or separately – just be sure you address both questions. Here are your questions for this week:
Part 1
As you listen to a vinyl record, how does the speed on the needle on the record change as the album progress (the needle move from the outside in)? How are compensations made (if any) for this?
Part 2
Go back and review freefall motion from your earlier study of kinematics. How is it easier (in most cases) to solve similar problems in freefall with energy here? What are two other examples where using energy might make solutions easier?
