Question

Which of the following are the characteristics of an inelastic collision?
I. Momentum is conserved.
II. Total energy is conserved.
III. Kinetic energy is conserved.
IV. All the forces must be of conservative nature. Choose the correct answer:

Q: Answer-Which of the following are the characteristics of an inelastic collision? I. Momentum is conserved....

In an inelastic collision Momentum is always conserved. Total energy including kinetic and potential energy is conserved. Kinetic energy is not conserved because some energy is converted into heat, sound, or deformation. Not all forces need to be conservative in nature. Thus, options I and II are correct.
