Solution
Correct Answer:
Bodies stick and kinetic energy decreases
A completely inelastic collision is characterized by:
- The colliding bodies sticking together after impact (vfinal1=vfinal2).
- Conservation of Linear Momentum (still holds).
- Maximum loss of Kinetic Energy. The lost KE is converted into heat, sound, or the potential energy of permanent deformation.
- Total energy is still conserved (Physics 101), but 'Kinetic Energy' is not (it decreases).
This medium difficulty physics question is from the chapter work, energy and power, covering the topic of inelastic collision. It appeared in the 2025 exam.
