There are two kinds of collision - elastic and inelastic. In an elastic collision, all the kinetic energy remains kinetic, though it might be transferred between objects in the collision. So the initially moving object could bounce back with the hit object staying in place, or the hit object might move and the initially moving object might stop. Or it might be a mix of both.
Not only things that you think of as elastic have elastic collisions. Very hard things sometimes tend to have elastic collisions too. Not only rubber balls but also billiard balls and baseballs tend to have elastic collisions.
The other type of collision is an inelastic collision. Some of the energy can remain in a kinetic form. The rest is converted to heat, sound, and breaking or deformation of the colliding objects.
Most of the mechanical (or kinetic) energy is converted to heat.
when one car hits another car
A steam engine would be one example, a motor car engine would be another.

Chemical energy into mechanical energy
If a car hits a stopped car and sets that car into motion and it hits another car, the first car is responsible for both cars. A stopped car is not responsible when someone sets it into motion and it hits another car.
Mechanical Energy
What does potential energy mean.
The energy stored in a car battery, or other cells or batteries, is chemical energy.
When a moving car hits a parked car, energy is transferred from the moving car to the parked car. The kinetic energy of the moving car is transferred to the parked car, causing it to move. Some energy is also converted into other forms, like sound and heat, during the collision.
Car because if a lightning hits the car the energy goes around the car but the tree can't absorb the energy
