Vedclass · Answer

(C) According to the law of conservation of linear momentum,if the net external force on a system is zero,the total momentum of the system remains conserved.When a ball hits the floor,the interaction between the ball and the Earth (floor) involves internal forces. Since there is no external force acting on the system of the ball and the Earth,the total momentum of the system is conserved.In an inelastic collision,kinetic energy is not conserved as some energy is dissipated as heat,sound,or deformation energy.Therefore,the mechanical energy of the ball is not conserved,and the total mechanical energy of the ball and the Earth is also not conserved due to the energy loss during the inelastic collision.

$A$ ball hits the floor and rebounds after an inelastic collision. In this case:
