rigidliikumine

Rigidliikumine refers to the movement of a rigid body. A rigid body is a theoretical object where the distances between any two points on the body remain constant, meaning it does not deform. In reality, no object is perfectly rigid, but this concept is a useful approximation in many areas of physics and engineering. Rigidliikumine can be divided into two fundamental types: translation and rotation.

Translation is a type of rigidliikumine where every point on the body moves along parallel paths. This means the body moves from one position to another without changing its orientation. If all points move in straight lines, it's called rectilinear translation. If all points move along curved paths, it's called curvilinear translation. In both cases, the body's orientation in space remains the same.

Rotation is the other fundamental type of rigidliikumine. In rotation, the body moves around a fixed axis or point. While points on the body may move at different speeds depending on their distance from the axis of rotation, all points traverse circular paths centered on that axis. A rigid body can undergo a combination of translation and rotation simultaneously, which is known as general rigidliikumine. Analyzing these combined motions is crucial in understanding the dynamics of objects in motion.
