Answer the following in brief:
Describe the energy transformations that occur in a pendulum to illustrate the law of conservation of energy.
Why does the bob eventually come to rest?
What happens to its energy eventually?
Is it a violation of the law of conservation of energy?
The bob forever. It involves rest as a result of resists its motion. The apparatus to beat this friction and stops once a while.
The law of conservation of energy as a result of the energy lost by the apparatus to beat friction is . Hence, the overall energy of the apparatus and also the encompassing system stay .
