Question

Describe the law of conservation of energy. Use a pendulum as an example.

Answer 1

Step-by-step explanation:

Explanation of the principle of the conservation of energy. ... For example, when a pendulum swings upward, kinetic energy is converted to potential energy. 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.

Answer 2

the amount of force or energy you put into something, you will always receive the same force back

Step-by-step explanation:

a pendulum will exert as much energy on the way down as on the way up.
