Question

why are we hurt more during a fall on a concrete structure than on a sand track

Answer 1

on a sand track the force acting on it reduce because momentum change take more time while falling as sand can be replaced by us

Answer 2

A cement structure is a hard structure and it has many irregularities. This surface is formed from hardening of a clay like substance. Which do not change shape on force.

On the other hand a sand track is mostly porose and changes its order when it is in contact with a force which makes the impact effect low.

This is why we hurt more on falling on a piece of concrete than a sand track.


I hope this helps you mark as the brainliest answer.
