Which energy is always conserved?
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.
Why doesn't the principle of mechanical energy conversation hold in situations when frictional forces are present?
Frictional forces result in the conversion of mechanical energy into heat energy. This transformation leads to a loss of mechanical energy in the system, causing the principle of mechanical energy conservation to not hold true in these situations.
what is the role of Joule's experiment in establishing the principle of conservation of energy?
total energy IS CONSERVED and the principle of conservation of energy does hold
Working models on conservation of energy?
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 conservation of energy explains that energy?
The law of conservation of energy states that all energy in the universe is conserved. It can not be created nor destroyed, but it can be interchanged between mechanical and non-mechanical energy.

Why doesn't the principle of mechanical energy conservation hold in situations when frictional forces are present?
In the case of friction, energy is wasted, i.e., mechanical energy is converted into useless energy, mainly heat.

What is the sum of potential and and Kinetic energy?
The sum of potential and kinetic energy is the total mechanical energy of an object. This total energy remains constant in the absence of external forces, according to the principle of conservation of mechanical energy.
What are the six principle of physics?
Principle of conservation of energy Principle of conservation of momentum Principle of relativity Principle of causality Principle of least action Principle of symmetry and invariance
Is the conservation of mechanical energy likely to hold in this scenario?
In most cases, the conservation of mechanical energy is likely to hold true in this scenario.
What is the law of conservation of energy in a electric iron?
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.
If you add an objects potential and kinetic energies you get its mechanical energy?
Yes, mechanical energy is the sum of an object's potential energy (due to its position) and kinetic energy (due to its motion). This total energy remains constant in the absence of external forces, according to the principle of conservation of energy.
Where the rockets operates on the principle?
