I was thinking about why bullet can break molecular bonds when it hits solid target despite the fact that the kinetic energy of the individual atoms that make up the bullet is less that the molecule bond energy threshold of the target.
For example, lets say we fire 300 m/s graphite bullet at teflon target. Carbon fluorine bond is 5.5 eV and carbon atom moving at 300 m/s velocity has 0.005 eV kinetic energy yet the graphite bullet is able to break the teflon carbon fluorine bonds.
How exactly do many carbon atoms with low kinetic energy join their energies together and break those bonds? Is this a phonon thing? Do they create together phonon wave with higher than 5.5 eV energy?
