Why is the momentum exchange very high for low distances?

For sufficiently short distances or large exchanges of momentum

While I think about it.. what exactly is exchanging momentum? The quarks?

    $\begingroup$ De Broglie? Does that mean the quarks are exchanging momenta all the time? Like scattering processes? $\endgroup$

Due to the de Broglie relation,

$$\lambda = \frac{h}{p},$$

wavelength and momentum are inversely proportional. This means that small distances are connected to large momenta and long distances are related to small momenta.
