No, according to the law of conservation of energy, energy cannot be created or destroyed, but can only change from one form to another. In any process, the total energy remains constant.

How can one calculate the amount of energy lost in a system?

To calculate the amount of energy lost in a system, you can use the formula: Energy lost Initial energy - Final energy. This means subtracting the final energy from the initial energy to find the difference, which represents the amount of energy lost.


What is the energy lost formula used to calculate the amount of energy dissipated in a system?

The energy lost formula used to calculate the amount of energy dissipated in a system is: Energy Lost Initial Energy - Final Energy.


What type of energy is lost energy on energy?

Lost energy in energy systems is often in the form of waste heat energy. This is energy that is not converted to useful work and is typically released into the environment, resulting in a loss of efficiency in the system. Strategies such as improved insulation, energy recovery systems, and better design can help reduce this lost energy.


From time to time people claim to have invented a machine that will run forever without energy input and develop more energy than it uses (perpetual motion). What is wrong with this claim?

Perpetual motion violates the laws of thermodynamics, specifically the first and second laws. The first law states that energy cannot be created or destroyed, only transferred or converted. The second law states that in any energy transfer or conversion, some energy is lost as heat, making it impossible to have a machine run forever without energy input and generate more energy than it uses.


Why do people think objects have lost energy when they slow down also state in what form of energy is lost?

People think objects have lost energy when they slow down because kinetic energy, which is the energy of motion, decreases as the object slows down. This lost energy is usually transformed into other forms of energy, such as heat or sound, through the process of friction or air resistance.
