This simply means that, as long as no mechanical energy is wasted or converted to other types of energy (and no other type of energy to mechanical energy), the total amount of mechanical energy doesn't change. Mechanical energy refers to the sum of kinetic and potential energy. Since energy losses and energy conversions do occur, this is not really a "law". In other words, the law of conservation of energy has not been known to be violated; conservation of mechanical energy is very easily violated.
The law of conservation of mechanical energy states that in a closed system, the total mechanical energy (sum of kinetic and potential energy) remains constant as long as no external forces are acting on it. This means that the energy within the system may change form between kinetic and potential energy, but the total amount remains constant.
The conservation law of energy states that energy cannot be created or destroyed, only transferred or converted. This law applies to all forms of energy, including mechanical energy. The conservation law of mechanical energy specifically refers to the total mechanical energy (kinetic + potential) of a system, which is constant as long as only conservative forces are acting on the system.
Mechanical energy is always conserved in a closed system. It can exist as potential energy (stored energy) and kinetic energy (energy of motion). This conservation principle is known as the law of conservation of mechanical energy.
The law of conservation of energy states that energy cannot be created or destroyed, only transformed. In an electric iron, electrical energy is converted to heat energy and mechanical energy, which enables the iron to press and smooth clothes. This conversion of energy follows the principle of conservation of energy.
An object sliding down a frictionless incline: as the object loses potential energy due to a decrease in height, its kinetic energy increases, demonstrating the conservation of mechanical energy. A pendulum swinging back and forth: as the pendulum moves from its highest point to its lowest point and back again, the total mechanical energy (potential + kinetic) remains constant, showing the law of conservation of mechanical energy.
The law of conservation of energy states that energy cannot be created or destroyed, only transformed or transferred. In machines, energy input is converted into various forms, such as mechanical energy, thermal energy, or electrical energy based on the machine's function. Thus, the total energy input must equal the total energy output in a machine, in accordance with the law of conservation of energy.

No, this is not a violation of the law of conservation of energy. The law states that energy cannot be created or destroyed, only transferred or converted into different forms. In this case, the energy not converted into mechanical energy is typically lost as heat, so the total energy is still conserved within the system.
The law of energy conservation states that, in a closed system, the amount of energy never changes. It stems from the classical physics principle that, while energy can be converted from one form to another (from kinetic energy (motion) to thermal energy (heat), for example) energy can neither be created nor destroyed..Since the different forms of energy are interchangable (kinetic to heat, for example), there is no law of conservation of mechanical energy as such. But in a hypothetical system without friction, air resistance, chemical reactions, etc, mechanical energy could be conserved.
Some common working models on conservation of energy include the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed. Other models include mechanical energy conservation, where the total mechanical energy of a system remains constant if only conservative forces are acting on it, and the principle of energy conservation in thermodynamics, which states that energy can change forms but the total energy in a closed system remains constant.
The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed. This means that the total energy in a closed system remains constant over time. This principle is fundamental in various physical phenomena, such as mechanical, chemical, and nuclear processes.
The law of conservation of mechanical energy states that the total mechanical energy (potential energy + kinetic energy) of a system remains constant if only conservative forces are acting on it. This means that the sum of the potential energy (PE) and kinetic energy (KE) in a system remains constant over time as long as no non-conservative external forces are present.
