1. How does the speed of a satellite change if the distance between it and Earth is increased or decreased?
2. How would one explain energy transfers quantitatively?
3. How would one explain energy conservation in a system and energy dissipation?
4. How would one explain the magnetic effect of a current?
Sorry if the questions seem a bit unrelated. It's because I'm revising for a test and these are some areas that I don't understand. All help is appreciated.
