Applying conservation of energy to harmonic oscillators. Harmonic oscillators satisfy energy conservation (like any systems!) Using energy concepts, we can analyze lots of aspects of oscillating motion. The analysis is easiest when there is no friction (dissipation) - in which case E

i don't understand. explain it clearly

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
