This concept is called the_________ throughout the experiment, the total amount of energy must ________ when potential energy goes down, kinetic energy _________ when potential energy goes up, kinetic energy______

Answer 1

Energy cannot be created or destroyed by ordinary physical or chemical processes. This concept is called the conservation of energy. Throughout the experiment, the total amount of energy must remain constant. When potential energy goes down, kinetic energy increases. When potential energy goes up, kinetic energy decreases.
