Cars absorb shock by use of their suspension system. This is made up of both the springs and shock absorbers / dampers.
The suspension system allows the wheels to move up and down separately to the car body / chassis when a car goes over a bump or pothole. When this happens the springs compress or stretch and so help resist the displacement and because of the way a spring works, the greater the displacement the more the spring resists it.
However to stop the spring "springing" back into it's original place too quickly and to prevent it vibrating and shaking the car repeatedly (which would be very uncomfortable and also make safe control of the vehicle much more difficult) they are also fitted with shock absorbers or dampers.
These are cylinders filled with a viscous fluid with a piston inside them. The piston is porous and permeable and so can pass through the fluid but the fluid resists the motion. As the velocity of the motion increases so to does the amount of resistance. This stops the spring being forced to move too quickly when hitting a bump, it also stops it rebounding to quickly afterwards and stops the spring from oscillating backwards and forwards. Essentially it dampens the movement - hence the use of the name damper.
Shock absorbers absorb shock by using hydraulic or pneumatic pressure. As a load is applied they compress and take most of the load.
mabye they "absorb shock!" 2nd Answer: In actual fact, shock absorbers do not absorb shock: the springs do that. The "shock absorbers" dampen rebound (Bouncing). In a bike, the spring is built right around the dampener part.
Earthquake shock absorbers do exactly what they say on the tin, they absorb some of the energy generated by an earthquake, in order to prevent structural damage. Most tall building in San Francisco are built on the shock absorbers, so that they can still stand after an earthquake

Their intended sole purpose is to absorb and damp spring oscillations or shock impulses leading to improved ride quality and vehicle handling.
Shock absorbers are a mechanical or hydraulic device designed to absorb and dampen shock impulses. Their intended sole purpose is to damp spring oscillations.
You have the cartilages in the joints, which act as mechanical shock absorbers. But then you have other functional shock absorbers. You have arches in the foot, which act as shock absorbers. Then when you jump down, you have that spring like movement of the legs. That act as a shock absorbers.

no, shock absorbers are in your knees and back. Some people have flat feet.
Bumbers have shock absorbers on them to absorb the shock of a minor impact (5mph) without causing significant damage to the car or the object hit. So, if you backed into a concrete wall while parking, the bumper would move with the shock absorbers - you might get a scuff on the paint; but if there was no shock absorber, the bumper or the mounting brackets would get bent (or the wall would break).
