gyorsaságmér

Gyorsaságmér is a Hungarian term that translates to "speed measurer" or "speedometer." It generally refers to a device used to determine the velocity of an object. Historically, this could encompass a variety of tools, from simple visual estimations based on time and distance to more complex mechanical or electronic instruments.

In modern contexts, particularly in automotive engineering, "gyorsaságmér" is synonymous with the speedometer found in vehicles. This instrument displays the instantaneous speed of the car, typically in kilometers per hour (km/h) or miles per hour (mph). Older vehicles often used mechanical speedometers, which relied on a flexible cable connected to the transmission to rotate a magnet. This rotation would then move a needle on a calibrated dial, indicating the speed. Contemporary vehicles predominantly employ electronic speedometers. These systems use sensors, often located at the wheels or transmission, to detect rotational speed, which is then converted into a digital signal processed to display the vehicle's velocity on a digital or analog gauge.

Beyond automobiles, the principle of a "gyorsaságmér" can be applied in various fields. For instance, radar guns used by law enforcement to measure vehicle speeds are a form of gyorskörségmér. In scientific research, specialized devices are used to measure the speed of everything from subatomic particles to astronomical bodies. The core function remains consistent: to quantify how fast something is moving.
