What is the meaning of Samadhi in Yoga?
Samadhi is the culmination of Ashtanga Yoga, representing a deep meditative state of blissful awareness. In this state, the practitioner transcends individual consciousness and connects with the universal spirit. This harmony results in an unshakable sense of peace, joy, and enlightenment.

Samadhi is the culmination of Ashtanga Yoga, representing a deep meditative state of blissful awareness. In this state, the practitioner transcends individual consciousness and connects with the universal spirit. This harmony results in an unshakable sense of peace, joy, and enlightenment. Unlike other stages requiring effort, Samādhi is an effortless and profound realization of unity with the self and the universe, embodying the ultimate goal of Yoga.

Angular momentum is a characteristic of rotating systems, and under certain conditions, it is conserved. The conservation of angular momentum is dependent on the fact that there is no net external torque applied to the system. Torque is a force that produces rotation and is a direct factor in the quantity of angular momentum. When there is no net external torque, the angular momentum will remain constant regardless of other external forces.
However, when some other torque applies on the system, it ruins this balance and leaves angular momentum to change. This principle can be noticed in everyday examples, such as figure skaters spinning faster once they pull their arms inside: no external torque is involved in the scenario. On the other hand, an external torque, such as friction or a push, applied to a rotating wheel changes its angular momentum.
External forces or impulses, per se, don’t change the angular momentum of a system unless they create torque. For example, a tangential force might change the linear motion of a system but wouldn’t change its angular momentum. Thus, whether or not external torque is applied to a system is the sole determining factor regarding whether its angular momentum is conserved. This is the most important concept in rotational mechanics and explains many of the phenomena occurring in the physical world.

A solid homogeneous sphere of mass and radius is moving on a rough horizontal surface. In this case, the sphere rolls and slides. The dynamics of the sphere are complex because of the interaction between translational and rotational motions. When the sphere moves, it experiences friction from the surface, which affects its motion. Frictional force at the point of contact between the sphere and the surface exerts a torque on the sphere, which is a factor changing the angular momentum of the sphere.
Total kinetic energy is not conserved during this type of motion because part of the energy is converted to heat due to friction. The angular momentum of the sphere about the point of contact with the surface can be conserved. This conservation takes place under certain conditions where no external torques act on the sphere about that particular point. Thus, even as the sphere rolls and slides, the angular momentum can be analyzed effectively using the point of contact as a reference. This situation highlights the interplay between different types of motion and the principles governing angular momentum in systems with friction. This is important to understand in the study of physics and engineering because one needs to know how objects move under various forces.
