in physics... when an object does work its loses energy and the energy gets transferred to an other object on which the work is being done... so when a car moves... the car is doing some work as it causes displacement and force is applied.. then where does the energy of the car gets transferred to???

Huston, we have a problem. The Internal combustion engine looses heat energy via the engine block and cooling system. The mechanical energy is lost in overcoming friction within the drive train; of air and ground resistance. In the case of up hill mobility energy is lost in overcoming gravity. I could break it down for you in finer parts but I think you realize what has happened to your energy.

are you referring to the energy that is extracted when the engine burns gasoline? Or the energy of the car in motion?Car engines are not every efficient. a great deal of the energy produced by the gas is lost to friction in the engine and heat. A great deal more is lost in the friction of the transmit ion and the wheel bearings. The rest is converted to kinetic energy, energy of movement. the motor must continuously supply more kinetic energy to the wheels because the enegry is lost through road friction and hills. It also loses the kinetic energy through friction and heat when the breaks are applied to stop it.
Cars are horribly in-efficient. They lose all the energy that they extract from the gas through friction and heat. The work of the car is overcoming friction.

When accelerating an automobile's work is transferred into the tires and the pavement as heat energy.
Tires get hot. Sometimes when you apply ALOT of energy, you can spin the wheels and smoke the tires, because they get so hot.
The pavement in the street also gets heat energy transferred from automobiles. Did you ever wonder why the snow melts on the streets before it does on the sidewalks and lawns in front of houses and businesses, it's because of all the heat energy being transferred from automobiles directly into the streets.

car does not do any work
work is done by force of friction ,friction is the force that causes movement of car
