energy cannot be created nor destroyed it can only change from one energy into another and this law is known as the: CONSERVATION OF ENERGY
law of conservation of energy
yes
The total mass and energy in the universe are considered constant according to the law of conservation of mass-energy. While mass can be converted to energy and vice versa, the total amount remains the same. This principle is a fundamental concept in physics.
Energy transformations involve changing energy from one form to another, while the law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. This means that in any energy transformation process, the total amount of energy remains constant.
Faraday showed hiow to do this in his Law: dB/dt = - DelxEv. A generator creates a changing magnet field and this induces an electric field in a circuit coupled to the changing magnetic.field. Hydroelectric plants use falling water to create the changing mag field.
Regarding a closed system (in which inputs and outputs are tightly controlled), the total energy you get from the system is always equal to the total energy you put in, even though some of it may be transduced by the system, like light changing to heat, electricity changing to motion, etc.
The total amount of energy in the universe is not precisely known, but it is believed to be constant due to the law of conservation of energy. This energy exists in various forms, such as light, heat, and matter, and is constantly changing and transforming within the universe.
The first law is also known as law of conservation of energy. It say that the energy can neither be created nor be destroyed but can only be transferred. Its is given by this equation dQ = dU + dW .
Because of the Law of Conservation of Energy, when you transform energy, any amount of energy that gets lost as one type of energy must needs appear - in the same amount - as another type of energy.
The law of conservation of energy states: "Energy can neither be created or destroyed, only changed in form." Energy transformation is changing it's form. Note: This law only holds in Newtonian physics. I Einsteinian physics is isn't valid.
Energy conversion is the process of changing one form of energy into another. It occurs in various ways such as mechanical to electrical energy in a generator or chemical to thermal energy in combustion. The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
The process of changing energy from one form to another is called energy conversion.
