No energy is lost, they're all simply transformed or dissipated into something else. Whether it's usable or not is another question.
For instance, no machine will ever be able to completely use all of it's energy productively, some will always be disspated as heat energy or sound, etc.
Energy is never lost. It always transfers to something else.
What are the energy transfers that happens in the ice on mount everest
i dont no
it decreases.
In general, energy is conserved during energy transfers. However, some energy may be lost as heat due to inefficiencies in the transfer process.
it decreases.
In a running race, the main energy transfers would be from chemical energy stored in the muscles to mechanical energy for movement. Also, some of the energy would be lost as heat due to friction between the feet and the ground.
Wasted energy is typically released as heat to the surroundings during energy transfers. This energy is not used to perform useful work and is often referred to as thermal energy. Efforts to minimize wasted energy loss during energy transfers are important in increasing efficiency and reducing energy costs.
Sunlight is radiation energy that transfers into heat energy
Energy is lost
It goes to the sun
In a train, energy transfers as electrical energy from the power source to mechanical energy in the locomotive, which propels the train forward. Some of this energy is also transferred to kinetic energy as the train travels, and friction between the wheels and the track causes some energy to be lost as heat.
