Pyörimisliikkeiden
Pyörimisliikkeiden, or rotational motions, refer to movements where an object or part of an object turns around a fixed axis. The axis can be internal, like the Earth's core, or external, as in a wheel rotating on a hub. Rotational motion is described by angular displacement, angular velocity, and angular acceleration, which are the rotational counterparts of linear kinematics.
The fundamental relationship between linear and angular quantities is given by s=rθ, where s is the arc
Rotational kinetic energy is expressed as K=½ Iω², distinct from translational kinetic energy but analogous in
Common applications of rotational motion include mechanical engines, flywheels, gyroscopes, and turbine blades. In everyday life,
