friction and work.
the car and wall get all hot and mangled.

Some of the kinetic energy is transferred to the pieces of the car as they fly off; some of it is dissipated as heat energy, the energy that creates sound waves from the crash, etc. However, the majority of the energy will be absorbed by the wall.
When two objects collide, their momentum is conserved, but not the kinetic energy; some energy is always converted into other forms of energy during an impact.

Ultimately ALL the kinetic energy ends up as heat. That includes the energy needed to deform the car, damage the wall, and even the tiny amount converted into sound.

Some of the kinetic energy would pass into the wall causing the damage and some would pas back through the car.

The majority is converted into heat energy. A tiny amount to light and sound which eventually revert to heat. Some may be converted to potential energy eg it it lifts the wall or distorts metal in a way that it can spring back. To say that the wall absorbs energy is true but not definitive. It will be absorbed but as heat, or as potential energy if the wall is moved upwards.

it converts into lots of different forms of energy, it converts into sound, ie the big bang you hear, also some heat is created as the metal bends and buckles.
alot of it gets absorbed by the wall, and the car, that's why bits of both go flying, it gets transferred to the small bits of wall the come off, and some energy stays with the bits of car that fly off.
modern car use the crumple zones to absorb the energy, they are designed to buckle and crumple so that the deceleration is less and the amount of force or energy the driver is exposed to, is the same, or less, but over a greater period of time
i hope this helps

Some of the kinetic energy is absorded by the wall and the rest is converted into heat energy.

most is tranfered into the wall (where the shock way gets further transfered to the foundations etc), some is converted into sound (the bang), some is converted into heat (as the metal bends in the car, friction on an atomic level occures creating heat) if there are sparks...metal scraping on the wall then some energy is transfered into light....it goes all over the shop...you get the idea.

The kinetic energy is expended in bending the metal of the car, and damaging, and possibly moving the wall or barrier.

The kinetic energy gets converted into heat energy and sound energy. Remember, energy can neither be created or destroyed, only changed.

Im a freshman, I haven't had physics yet, but would't the potential energy of the wall be greater than that of the car. So if the kinectic energy of the car were greater than that of the wall, would't the car just go through the wall? I assuming now that the car's kinectic energy is just transfered to the wall. I believe that this is correct but by no means am I exactly sure.
