Question

Which best explains what happens to the motion of the pendulum due to the law of conservation of energy? The pendulum will slow down and eventually stop moving as the mechanical energy transforms to thermal energy. The pendulum will slow down and eventually stop moving as the mechanical energy disappears. The pendulum will continue moving at the same speed because mechanical energy is created as the pendulum moves. The pendulum will slow down but will not stop moving because some of the mechanical energy is destroyed.

Answer 1

Option A is correct. The pendulum will slow down and eventually stop moving as the mechanical energy transforms to thermal energy.

What is the law of conservation of energy?

According to the Law of conservation of energy. Energy can not be created nor be destroyed it can transfer from one to another form.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

When the pendulum is executing the to and fro motion the air resistance is also acting on it. Due to that air resistance, the energy is utilized to overcome resistance and convert it into thermal energy,

Hence option A is correct. The pendulum will slow down and eventually stop moving as the mechanical energy transforms to thermal energy.
