SUMMARY

The discussion centers on the relationship between momentum and the force of impact, specifically in the context of Newton's Second Law of Motion. When a soccer ball is kicked, its elastic properties allow it to deform, resulting in a longer interaction time and less force transmitted to the foot. In contrast, a rock, being less elastic, transmits a greater force due to its rigidity and shorter interaction period. The mass of the objects also plays a crucial role in determining the impact force experienced.

A question about momentum ??

I have a question about momentum with respect to Newtons Second Law of Motion.When We hit a soccer ball our foot does not hurt but when we hit a rock our foot hurts badly.What is the reason of this ? I think it is related to reaction time

Yup, if you view a soccer ball being kicked in slow-motion, you will actually see it deform as it is elastic. The rock however, is much less elastic and hence the period of the interaction is significantly less.
 


The mass of the two objects would also play a part as well. Compare the mass of a soccer ball to a "rock".
