decelálást

Decelálás is a Hungarian term that translates to "deceleration" in English. It is most commonly used in the context of physics and motion, referring to a decrease in speed or velocity. This can occur due to various forces acting against the direction of movement, such as friction, air resistance, or braking.

In everyday life, deceleration is a familiar phenomenon. When a car brakes, its speed decreases, which is a form of deceleration. Similarly, when an object is thrown upwards, gravity acts against its motion, causing it to decelerate until it reaches its peak height and begins to fall back down.

In scientific contexts, deceleration is often quantified by measuring the rate at which the velocity changes. This rate is known as negative acceleration. For example, if an object is moving at 10 meters per second and its speed decreases by 2 meters per second every second, its deceleration is 2 meters per second squared. The negative sign indicates that the acceleration is in the opposite direction to the velocity, thus causing a reduction in speed.

Understanding deceleration is important in various fields, including engineering, where it is crucial for designing safe braking systems for vehicles, and in sports, where athletes may employ techniques to decelerate quickly.
