Chapter 15 Periodic Motion
... ❹ EVALUATE RESULT I made two assumptions to derive my answer. The first is that gravity can be ignored. Indeed, taut strings tend to be straight, indicating that gravity (which would make the strings sag) doesn’t play an appreciable role. The other assumption I made was that the length of the string ...

... Mechanical Energy. In this laboratory, both methods will be used in determining the mechanical energy “lost” due to the dissipative force of friction. It is important to remember that the energy is not actually gone; rather it is converted into some other form. When using the Law of Conservation of ...
