During an inelastic collision,
During an inelastic collision,
Options
- Athe kinetic energy initially increases and subsequently decreases
- Bthe kinetic energy remains constant
- Cthe initial kinetic energy matches the final kinetic energy
- Dthe final kinetic energy is lower than the initial kinetic energy
Correct answer
D. the final kinetic energy is lower than the initial kinetic energy
Step-by-step solution
In an inelastic collision, the kinetic energy of the system is not conserved. A portion of the initial kinetic energy is dissipated in the form of heat, sound, or deformation energy during the collision.
Therefore, the final kinetic energy of the system is always lower than the initial kinetic energy.
Therefore, the final kinetic energy of the system is always lower than the initial kinetic energy.
