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.

Can machines increase energy?
Machines themselves cannot inherently create energy; they can only convert energy from one form to another. Machines can be used to harness energy from different sources such as fossil fuels, wind, or solar power, but they cannot create energy on their own.
What is the energy not available to do work?
The energy not available to do work is known as wasted energy or unusable energy. It is typically lost as heat during energy conversions and cannot be harnessed to perform useful work. Examples include frictional losses in machines or heat dissipation in electrical circuits.
Is a machine a device that create energy?
No, a machine is a device that uses energy to perform work or tasks. Machines can transform energy from one form to another to carry out specific functions, but they do not create energy.
What can't simple machines do?
Simple machines cannot create energy; they only change the direction or magnitude of a force. Additionally, they cannot violate the law of conservation of energy, meaning they cannot create more energy than they receive.
Can a machine make energy?
No, machines cannot create energy. Instead, machines can convert one form of energy into another, such as a generator converting mechanical energy into electrical energy. The law of conservation of energy states that energy cannot be created or destroyed, only transformed.
Does the second Law of Thermodynamics contradict the First Law?
No, the Second Law of Thermodynamics complements the First Law by providing information about the directionality and efficiency of energy transformations. The First Law states that energy is conserved in a system, while the Second Law explains the natural tendency of energy to disperse and increase entropy in a closed system over time.

How do machines create energy?
It is wrong to say machines create energy. Machines have to be given energy to make them effective. This could be electric energy, solid liquid or gaseous energy, thermal energy, mechanical energy (like a flywheel for example). It may be possible to design machines which will search for their energy by themselves, some robots may already have achieved. Remember we humans are also machines, but we get our energy from digesting food.
Can energy be destroyed but not created?
Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.

An airplane changes energy into different forms The total amount of energy does not?
The total amount of energy doesn't change. However, some useful energy will be converted into unusable energy.The total amount of energy doesn't change.

Can energy be regenerated?
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.

What uses energy and can create energy?
A power plant or generator can create energy by converting one form of energy into another. Energy-consuming devices like appliances, machines, and vehicles use energy to perform tasks or operations.
What is the amount of unusable energy in a system called?
The amount of unusable energy in a system is called entropy. Entropy measures the level of disorder or randomness in a system and represents the energy that cannot be converted into useful work.
