state the law of conservation of energy of pendulum.discuss the energy changes of the Bob which is allowed to oscillate. why does the Bob eventually come to rest
Answers
Answer:
The illustration is below in attachment...It comes to rest because air resistance resists its motion. The pendulum loses its kinetic energy to overcome this friction and stops after some time.
The law of conservation of energy is not violated because the energy lost by the pendulum to overcome friction is gained by its surroundings. Hence, the total energy of the pendulum and the surrounding system remain conserved.
Explanation:
Answer:
the energy cant be destroyed but can be changed from one form to another
the bob suspended in a pendulum remains oscillate till all its energy is used up the energy applied to the bob t make it oscillate is not finished or destroyed but is has been used by friction. say this energy is reacted against friction as the frictional force has been stopping the bob.
