Question

Explain that energy is always conserved by taking the example of
a pendulum​

Answer 1

Answer:

When the pendulum stops briefly at the top of its swing, the kinetic energy is zero, and all the energy of the system is in potential energy. When the pendulum swings back down, the potential energy is converted back into kinetic energy. ... The truly conserved quantity is the sum of kinetic, potential, and thermal energy.
