At that point, all of the energy is in the force. But since force is transitory, while motion is not, force must be multiplied times time to produce a quantity of motion. Therefore, creating or amplifying force is creating or amplifying energy. The conservation of energy is not an absolute phenomenon. Gravity creates force and energy.
Levers amplify force and energy.
To conserve an abstraction, when energy is supposed to be created or amplified, demonstrates that the abstraction is not energy. In other words, the analysis of mv removes much of the complexity of nature, besides contradicting the logic. Its lack of a relationship to actual events results in the basic questions being erased rather than answered. The basics of energy are nearly unstudied because of the obstacles created by the analysis of mv .
