First
energy exists in several forms and is required for growth, reproduction,movement, cell or tissue damage repair, and other activities of whole organisms, or molecules. -sun is the ultimate source of energy on Earth :)
The byproduct of energy transformations is heat, which is released into the environment. This is due to the second law of thermodynamics, which states that some energy will always be converted into an unusable form (in this case, heat) during energy transformations.
You can look the up, for example in Wikipedia, for a detailed definition. Informally, you can think of them as two "laws of energy": 1) Energy conservation (energy can't be created or destroyed) 2) Usable energy is constantly being converted into unusable energy. This will continue until no more usable energy is left.
True
The law of energy conservation, also known as the first law of thermodynamics, has never been broken. It states that energy cannot be created or destroyed, only transformed from one form to another. This principle remains a fundamental concept in physics.
According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.
This statement is based on the second law of thermodynamics, which states that in any energy transformation, some energy is lost as waste heat and cannot be converted back into usable energy. This principle underlies many natural processes and technological systems.

Perpetual motion machines are theoretical machines that aim to create unlimited energy without an external source but violate the laws of thermodynamics, making them impossible to create in reality. Other examples of machines that create unusable energy could include inefficient or poorly designed machines that waste energy in the form of heat, noise, or other non-usable forms.
Not at all. The First Law states that energy is conserved - you can't create energy out of nothing, or make it disappear. The Second Law distinguishes usable from unusable energy, and states that the amount of unusable energy will increase over time - but the total (usable plus unusable energy) will still remain constant.Not at all.

You must be referring to the two Laws of Thermodynamics. Stated in terms of energy: 1. The First Law of Thermodynamics is the Law of Conservation of Energy, meaning that energy can not be created or destroyed. 2. However, useful energy is continuously being converted into unusable energy. This is irreversible. This is the Second Law of Thermodynamics.
A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
