Question
Write a note on inelastic collision.
✓
Answer
$1.$ A collision is said to be inelastic if there is a loss in the kinetic energy during collision, but linear momentum is conserved.
$2.$ In an inelastic collision, $m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2.$
$3.$ In an inelastic collision,
$\sum K \cdot E _{\text {.initial }} \neq \sum K \cdot E _{\text {.final }}$
$4.$ The loss in kinetic energy is either due to internal friction or vibrational motion of atoms causing heating effect.
