Can mechanical energy be conserved?
When and how is mechanical energy not conserved?
When is mechanical energy produced? How is mechanical energy produced? Is the law of conservation of energy a relative concept? What is the significance of the law of conservation of energy? Why is energy conservation vital? Is the law of conservation of energy false? If energy cannot be created nor destroyed, only transferred, where did it come from? What is conserved momentum? How nonconventional energy is differ from conventional energy? Is there a possibility that the law of conservation of energy is wrong? What are some examples of the law of conservation of energy? What is the derivation of the law of conservation of energy? If energy can neither be created nor be destroyed, then who created energy? Is it true that energy actually can be created and/or destroyed? If energy is neither created nor destroyed, what happens to the energy within our bodies and brains when we die? Can energy be created in a non-energy environment? Can energy be created? Energy can neither be created nor destroyed! Can this be proved wrong? How do you convert mechanical energy to chemical energy? If energy cannot be created. can force be created higher than the energy required? Are there exceptions to the law of conservation of energy (known, or suspected)? How did they know that momentum is conserved? How do transformers not break the law of conservation of energy? How energy can be created? Can energy/matter be created/destroyed? What is energy? How is it created? If energy never gets lost, why can't we create a machine that works forever? How energy was created at first? Is it true that matter/energy actually can be created and/or destroyed? What must be done with batteries so that the chemical energy in them is transformed into electrical energy?
