When you make a complete stop in an auto, you experience 'kickback' when the auto comes to rest. What force is at work to produce this 'kickback'? I tried a few peeps for an answer but they told me life is all about momentum. Their dogs for mess'n with me.

I think it is due the inertia.According the first law of Newton: a body will be in motion unless something stops it.
So when go in the car you experience motion and the car stops you continue moving.

So would that be a force from stored energy since it's inertial?

aravindg · Answer

It will be due to the kinetic energy the body possesses even after the auto is brought into halt. Inertia is the key word here.

Inertia is not the solution, in my view. It has rather to do with a form of elastic potential energy by the seat belt and the muscles.

This is all great stuff and appreciate all the comments. That said, the kickback sensation that is felt after you come to a complete dead stop, i.e. wheels have completely stopped no movement in either direction is my concern. This kickback occurs whether your body is secured by a seat belt or not. This force is experienced by the entire car not just the people inside. I would like to know the 'force' that is creating the 'energy' to produce the 'kickback' sensation. Kinetic energy? What do you think the force is to create the energy?

i think this force is due to change in acceleration of you body.
