The correct statement that describes why the student is incorrect is: Energy is converted from other forms, not created.
The correct statement is: Energy is converted from other forms, not created.
Explanation: According to the law of conservation of energy, energy cannot be created or destroyed, but it can be converted from one form to another. When an object falls through the air, its potential energy is converted into kinetic energy, which is the energy of motion. The object gains speed as it falls because the potential energy is being converted into kinetic energy. Therefore, the increase in speed does not imply the creation of new energy, but rather a conversion of existing energy from one form to another.
