Answer: Potential energy is converted to kinetic energy and back again.
Explanation:At points 1 and 3, the pendulum stops moving, and its mechanical energy is purely potential. At point 2, the pendulum is moving the fastest, and its mechanical energy is purely kinetic. Therefore, as the pendulum moves from point 1 to point 3, its potential energy is first converted to kinetic energy, then back to potential.
As the pendulum moves from point 2 to point 3, what happens to its mechanical energy "potential energy is converted to kinetic energy and back again".
What is mechanical energy?
The combination of kinetic as well as potential energy in such an object employed to perform a specific task is known as mechanical energy.
What is potential energy?
Potential energy is the energy which is collected in a system and is determined by the relative positions of individual parts of the system.
