A female student in the front row raised her hand.
"Yes, Rina?" The middle-aged woman turned to the girl who had raised her hand.
"How does this diagram relate to the speed of a freely falling object?" Rina asked.
"That's a good question," the middle-aged woman replied.
"This diagram helps us understand how potential energy is converted into kinetic energy as an object falls. When the object is at the peak of this parabola, its potential energy is at its maximum. As it falls, its potential energy decreases and is converted into kinetic energy."
The middle-aged woman explained carefully to each student who asked a question. She had a strong passion for teaching. Initially, she was very worried about not having a place where she could teach and her skills being needed. But now, she could even earn a significant amount of energy crystals for her family.
