It just depends on how quickly it stops. In some crashes the vehicle may go on out of control for some distance, in head-on crashes it will stop very quickly
Yes, the kinetic energy of a vehicle dissipates rapidly in a crash due to sudden deceleration forces. This rapid dissipation of kinetic energy is what leads to deformation of the vehicle and potentially serious injuries to occupants. Safety features like crumple zones and airbags are designed to help absorb some of this energy and protect passengers.
When the kinetic energy of a crash is absorbed by crushing the metal of the vehicle, this is due to the principle of energy conservation. The deformation of the metal dissipates the energy of the collision in the form of heat and sound, reducing the impact forces on the occupants inside the vehicle. This is why vehicles are designed with crumple zones to effectively manage and reduce the energy of a crash.
The vehicle's momentum decreases quickly as it comes to a stop upon impact with the wall. The force of the crash dissipates the vehicle's kinetic energy, transferring it to the wall and causing damage to both the vehicle and the wall.
No, the kinetic energy of a moving vehicle actually increases with its speed. Kinetic energy is proportional to the square of the velocity, so the faster the vehicle moves, the more kinetic energy it has.
In a bicycle, kinetic energy is transformed into other forms of energy. When you apply brakes, the kinetic energy is converted into thermal energy due to friction between the brake pads and the wheel rims. This heat energy then dissipates into the surroundings.

Kinetic energy is extra energy resultant of motion. So, a moving vehicle has kinetic energy.

When a machine stops, the kinetic energy is dissipated as heat due to friction and other forms of resistance. As the machine comes to a halt, the kinetic energy is transformed into thermal energy and eventually dissipates into the surroundings.
Well, it really depends how the brakes are designed to work. In principle, a brake can, for example, convert part of the kinetic energy into an electrical current, which loads a battery.But yes, in the usual design, the kinetic energy is converted to heat energy.
The speed of the vehicle and its mass are the two factors that will affect the amount of kinetic energy. Kinetic energy is directly proportional to both speed and mass, so an increase in either will result in a greater amount of kinetic energy.
In a standard vehicle, the braking system transforms the kinetic energy into heat energy through friction between the brake pads and the brake rotors. This heat dissipation slows down the vehicle by reducing its kinetic energy.
Kinetic Energy
When you bring your bicycle to a stop, the kinetic energy is converted into other forms of energy, such as heat and sound. Friction between the bike's wheels and the ground dissipates the kinetic energy as heat, while the braking mechanism may also convert some of it into sound energy.
