There are two types of momentum. The above momentum is called the linear momentum. This happens in a straight motion. Rotational movements take into account angular velocity and moment of inertia. The moment of inertia is mass. Mass inhibits acceleration in a straight motion, and a moment of inertia interferes with rotation in rotation. For example, in the case of conservation of angular momentum, let’s say a person is spinning. Holding both hands together is faster than stretching both hands.
When stretched, the moment of inertia is higher, so the angular velocity is lower, and when stored, the moment of inertia is lower and the angular velocity is higher. This shows that the angular momentum is stable. Closed systems and energy; The principles of momentum stability are some of the most useful fundamentals in the study of relativity and quantum physics, and in the real world, engineers are often considered when designing various devices.
