Impact energy is the amount of energy required to fracture or break a material under a sudden applied force or load. It is used in materials science and engineering to assess a material's toughness, its ability to absorb energy and resist breaking when subjected to rapid stress, such as a collision or blow.

\( E_i \;=\; \frac{1}{2} \cdot m \cdot v^2 \) (Impact Energy)
\( m \;=\; \dfrac{ 2 \cdot E_i }{ v^2 } \)
\( v \;=\; \sqrt{ \dfrac{ 2 \cdot E_i }{ m } } \)
