Energy is in discussion since the 1800 when the term appeared first. It is now well known in practical terms and its conservation proven in many experiments. But what is the theoretical definiton that answers all the questions related to energy.
Energy is a fundamental concept in physics, referring to the capacity to do work or produce heat. It comes in various forms and can be categorised into different types, such as kinetic energy (energy of motion), potential energy (energy stored in an object due to its position or state), thermal energy (energy associated with the temperature of an object), chemical energy (energy stored in the bonds of atoms and molecules), electromagnetic energy (energy carried by light and other electromagnetic waves), and more.
Matter can absorb energy through various processes, depending on the type of energy involved. For example:
The second law of thermodynamics invokes the idea that mass density varies according to the criteria of traditional physics, but quantum physics does not consider the residual energy of the zero-point field (ZPE). As we observe in the Casimir effect between two plates, a phenomenon occurs at the center generating residual energy capable of storing infinite energy. This translates into the fact that there is still a lack of knowledge to create precise measuring devices. Encompassing energy is a field that we are gradually connecting to its direct relationship with magnetism or quantum electrodynamics (QED).
