felgyorsulása

Felgyorsulása is a Hungarian term that translates to "acceleration" or "speeding up" in English. It describes the process of an object or system increasing its velocity or rate of change over time. This phenomenon is fundamental in physics and is governed by the principles of kinematics and dynamics.

In a physics context, felgyorsulása is typically represented by the symbol 'a' and is a vector quantity, meaning it has both magnitude and direction. Its standard unit of measurement in the International System of Units (SI) is meters per second squared (m/s²). Acceleration occurs when a net force acts upon an object, causing its mass to change its state of motion. This change in motion can manifest as an increase in speed, a decrease in speed (often referred to as deceleration or retardation), or a change in direction.

The concept of felgyorsulása is crucial for understanding motion, from the simple movement of a falling object to the complex orbital mechanics of celestial bodies. It is a key component in the equations of motion that describe how objects behave under the influence of forces. For example, the acceleration due to gravity is what causes objects to fall towards the Earth at an increasing speed. Beyond physics, the term can also be used more generally to describe any process that is becoming faster or more intense.
