pyörähtämisen
Pyörähtämisen, meaning "spinning" or "rotating" in Finnish, is a fundamental concept in physics and everyday life. It describes the motion of an object around a central axis. This axis can be internal to the object, as in the rotation of a planet on its axis, or external, as in the orbit of a planet around a star.
The speed of rotation is measured by its angular velocity, often denoted by the Greek letter omega
In physics, pyörähtämisen is closely related to concepts like angular momentum, a conserved quantity for isolated
In practical terms, pyörähtämisen is all around us. Wheels on vehicles, spinning tops, propellers, and even the
