Tömegmerevség

Tömegmerevség, a Hungarian term, translates to mass inertia or simply inertia in English. It is a fundamental concept in physics that describes an object's resistance to changes in its state of motion. This means that an object at rest will tend to stay at rest, and an object in motion will tend to stay in motion with the same velocity, unless acted upon by an external force. The greater an object's mass, the greater its inertia, and therefore the more force is required to accelerate or decelerate it. This principle is encapsulated in Newton's first law of motion, often referred to as the law of inertia. Tömegmerevség is not a force itself, but rather a property of matter. It is why it is harder to push a heavy object than a light one, and why a moving car takes a longer distance to stop than a bicycle. Understanding tömegmerevség is crucial for analyzing motion, forces, and the behavior of physical systems. It plays a significant role in fields ranging from classical mechanics to astrophysics.
