gyorsítási

Gyorsítási is a Hungarian term that translates to "acceleration" in English. It is commonly used in physics to describe the rate of change of velocity. This change can involve an increase in speed, a decrease in speed (also known as deceleration), or a change in direction. Acceleration is a vector quantity, meaning it has both magnitude and direction.

In classical mechanics, acceleration is defined by Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass. Mathematically, this is expressed as F = ma, where F is the net force, m is the mass, and a is the acceleration.

The unit of acceleration in the International System of Units (SI) is meters per second squared (m/s²). For example, if an object's velocity increases by one meter per second every second, its acceleration is 1 m/s².

The concept of "gyorsítási" is fundamental to understanding motion and the behavior of objects under the influence of forces. It is applied in various fields, including engineering, astronomy, and everyday life, such as describing how a car speeds up, how a planet orbits a star, or how gravity causes objects to fall.
