Rörelseväg

Rörelseväg, often translated as "path of motion" or "trajectory," refers to the complete course taken by an object as it moves from one point to another. It encompasses all the intermediate positions occupied by the object during its displacement. This concept is fundamental in physics and kinematics, providing a detailed description of an object's motion beyond just its starting and ending points.

The rörelseväg can be a straight line, such as the path of a ball thrown directly upwards and falling back down, or it can be curved, like the arc of a projectile or the orbit of a planet. The shape and length of the rörelseväg are distinct from the object's displacement, which is the straight-line distance and direction from the starting point to the ending point. For instance, an object moving in a circle completes a rörelseväg that is the circumference of the circle, but its displacement after one full revolution is zero.

Understanding the rörelseväg is crucial for calculating quantities like distance traveled, average speed, and the work done by forces. It is often represented graphically as a curve on a coordinate system, illustrating how the object's position changes over time. In more complex scenarios, the rörelseväg can be described by mathematical equations that precisely define the object's coordinates at any given moment.
