## What’s harder to break ice or concrete?

## Can a human punch through a brick wall?

The reason normal people can ‘t punch into a brick wall to the depth suggested by Newton’s approximation is they can ‘t accelerate their fists sufficiently to make the cohesion of the brick wall insignificant.

## Can humans break concrete?

A wall, no you can ‘t break a concrete wall with your hand. Have you ever seen a steel jackhammer used to break break concrete, it requires a steel chisel point.

According to this the most force its possible for an elite boxer to punch with is 6316N.

## Is ice harder than wood?

You can hit ice with just enough force to cause a fracture to grow and the ice may break due to its own weight. With wood, the strands are more ‘glued’ together by sap, moisture, etc. The force must continue through the wood to rip it apart. As thickness increases, I’d say that wood is harder to break than ice.

## Is ice harder than rock?

Thus ice is softer than rock. It is because the ice’s hardness measured on the Mohs scale of hardness of minerals is 1.5 while the hardness of the minerals ranges from 1 to 10. Thus all minerals are harder than the ice.
