For an inelastic collision between two objects, which one among the following statements is correct?
General SciencePhysics
- AThe kinetic energy remains conserved, but not the momentum.
- BThe momentum remains conserved, but not the kinetic energy.
- CBoth the kinetic energy and the momentum remain conserved.
- DNeither the kinetic energy nor the momentum remains conserved.
Explanation
In an inelastic collision the total momentum of the system is conserved, but part of the kinetic energy is converted into heat, sound or deformation, so kinetic energy is not conserved. Hence B.
