Modern cars are fitted with headrests (and recommended to be kept at a height that is level with the occupant's neck and head) in order to protect the neck and head from whiplash in the case of a collision. In a collision the use of an appropriately adjusted headrest will end the backwards motion of the head when a force acts upon impact.
i hope this helps, this is like my first answer on here ahah :)

What are headrests in the car for?
They are to rest your head against so that the neck muscles do not have to support the head in the forward looking position all the time. This is obviously important for the driver. Also, in the case of a shunt, the headrest will minimise whiplash injury be preventing the head from being pushed back.
What are the types of mechanical work?
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
How does input work and out put work affect the efficiency of a simple machine?
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
The work that the simple machine does is called the work?
the work a machine does is the work output what it takes to do the work is the work input

Passive headrests are fixed, non-adjustable headrests typically found in car seats. They are designed to provide support and protection for the head and neck in case of a rear-end collision by helping to limit the movement of the head during impact.

How do head rest on a car seats work by using laws of physic?
Headrests don't work. Headrests don't move. If they don't move, they don't perform work. That is a law of physics. Work is defined as "Force through a distance". ...but.... You probably are asking how they function relative to the laws of motion. The headrest prevents your head from continuing in its current state of motion when the car is struck from behind. Without the headrest, your head snaps backward relative to the seat and strains the neck. That sort of injury is called "whiplash".
