When the car has no gas, no energy is used and no energy is produced.
Basically, in physics, total energy is always conserved. Of course, it is possible for some of the energy from a car to go somewhere else.
If you think of a car, fuel is burnt to make the car move. Chemical energy into kinetic energy. The reason the car stops when the fuel runs out is because the car is having to work against forces acting against it like friction with the road, air resistance and gravity acting on it's own mass.The cars motion or kinetic energy is converted into kinetic energy in the particles in the air and heat due to friction.
Most of the mechanical (or kinetic) energy is converted to heat.
it stops working
the elastic potential energy of the spring on the mouse trap is changed to kinetic energy, causing the car to move. The kinetic energy in turn changes to thermal energy as friction causes the car to come to a halt
The engine doesn't have to use as much fuel when the car is traveling downhill.
When a car slows down, its kinetic energy decreases as it loses speed. This kinetic energy is converted into other forms of energy, such as heat generated by the brakes and friction between the tires and the road. Thus, energy is conserved through this conversion process.
When brakes are used to stop a car, friction is created between the brake pads and the brake rotors, which slows down the rotation of the wheels. This friction converts the kinetic energy of the car into thermal energy, dissipating heat in the process. This heat is what ultimately stops the car by reducing its speed.
Check for vacuum leak
it stops working until it gets changed again. but if its a hybrid then the petrol kicks in
Total momentum
In an elastic collision, all initial kinetic energy is fully restored as final kinetic energy. where nothing is converted into noise, heat or any other form of energy. In an inelastic collision, kinetic energy is "lost" to thermal or sound energy.
