the back of the jaw is attached by the muscles, how can the point of attachment be related to the force that the teeth at the back exert? Pivot? Lever? Distance and forces change to suit the need like WRENCH ???

Leverage, like a pair of scissors

The jaw joint (the fulcrum) has the operating muscle (the effort component) just in front of it. Whatever you're chewing on (the load component) has to be as close to the fulcrum as you can get it to have the maximum force applied to it by the effort component.
Irrespective of where the jaw muscles are, therefore, the greater force is applied to the load the closer it is to the fulcrum i.e. the further back in the jaw that it is.

Those teeth have a larger top surface area, so they have more force - A car hitting you at 50 mph will hurt you worse than a bug hitting you at 50 mph because it has more surface area applying the force...
Just my two cents... but probaly wrong as I did badly in all science classes

It's like cracking nuts. If you put the nut closer to the base (or in the case of your mouth, the jaw), there is more power with less effort.

It is a combination of having more surface area and more leverage. Judging from what you said, you seem to understand it already.

it works like a pair of pliers. yes lever. anyway, get a pair of pliers and grab something. now turn them around and try to use them backwards and pick something up. you'll have the answer to your question.

back teeth r broader n thus hav more surface ares then the front teeth.

Because they are bigger than the teeth up front.
