teckenconventionen
Teckenkonventionen, often translated as "sign conventions," refers to a set of rules used in physics and mathematics to assign positive or negative signs to certain quantities. These conventions are crucial for ensuring consistency and accuracy in calculations, particularly in areas like optics, mechanics, and electricity.
One of the most common sign conventions is used in optics to describe the focal length and
In mechanics, sign conventions are applied to quantities like displacement, velocity, acceleration, and force. Often, a
Similarly, in electricity and magnetism, signs are used to denote charge polarity (positive and negative), current
