General Flashcards
What is energy efficiency?
Energy Efficiency is the ratio of useful output energy to the total input energy.
What is a system?
Objects or group of objects that interacts during the energy transfer.
What is power?
Power is the rate at which energy is transferred.
What is filament bulb?
Filament bulb is a bulb that has a thin coil of wire called the filament. The electric current passes through the filament, heating the filament until it glows and transfer to light energy as a result.
What happens to the kinetic store of the ball that roll down a hill?
The kinetic store of the ball will increase as the gravitational potential energy is transferred to kinetic.
What is dissipated energy?
Dissipated energy aka wasted energy is the energy transferred to non-useful stores, it is the energy that is lost to the surrounding.
