Statement-1 : In a perfectly inelastic collision, the kinetic energy of the system is always conserved.
Statement-2 : In a perfectly inelastic collision, the colliding bodies stick together and move with a common velocity after collision.

Question

Statement-1 : In a perfectly inelastic collision, the kinetic energy of the system is always conserved.

Statement-2 : In a perfectly inelastic collision, the colliding bodies stick together and move with a common velocity after collision.

TestHub · Accepted Answer

Statement-1 is false. In a perfectly inelastic collision, kinetic energy is NOT conserved; there is a maximum possible loss of kinetic energy, converted into other forms like heat or sound. Statement-2 is true. By definition, in a perfectly inelastic collision, the colliding bodies stick together and move as a single combined mass with a common final velocity.
