A ball hits the floor and rebounds after an inelastic collision. In this case
If the ball were to strike the floor, hit the ground and rebound as in an inelastic collision, it would follow that the total momentum of the Earth and the ball is conserved. However, in the inelastic collision, some of its kinetic energy becomes other types of energy like heat or sound that causesRead more
If the ball were to strike the floor, hit the ground and rebound as in an inelastic collision, it would follow that the total momentum of the Earth and the ball is conserved. However, in the inelastic collision, some of its kinetic energy becomes other types of energy like heat or sound that causes loss of mechanical energy but the system with both Earth and the ball together conserves their total momentum.
This is a basic principle in physics, which states that the total momentum of a closed system remains constant if no external forces act upon it. In this case, the ball and the Earth constitute a closed system, and the internal forces during the collision do not affect the total momentum.
Note that, although momentum is conserved, mechanical energy is not in inelastic collisions because kinetic energy is converted into other forms of energy. Thus, the correct answer is that the total momentum of the ball and the Earth is conserved.

The transition from Dhārana to Dhyāna occurs as focused concentration on a single object becomes effortless. Dhārana requires discipline and mental effort, but when concentration flows seamlessly without distraction, it evolves into Dhyāna. This meditative absorption fosters profound mental stillness and heightened awareness, aligning the mind with inner tranquility. Dhyāna deepens self-awareness and prepares practitioners for Samādhi, the ultimate state of spiritual unity and enlightenment in the Yogic journey.
