decelación

Decelación is a term used in physics and engineering to describe the process of slowing down or decreasing speed. It is the opposite of acceleration, which refers to increasing speed. Decelación can occur due to various forces, such as friction, air resistance, or the application of brakes. When an object decelerates, its velocity decreases over time. This change in velocity over time is also known as negative acceleration.

In practical terms, decelación is a fundamental concept in the design and operation of vehicles, aircraft, and many other mechanical systems. Understanding and controlling decelación is crucial for safety and efficiency. For example, the braking system of a car is designed to generate a controlled decelación, bringing the vehicle to a stop safely. The rate of decelación can be measured and is often expressed in meters per second squared (m/s²) or feet per second squared (ft/s²), with a negative sign indicating a decrease in speed. The principles of decelación are also important in fields like astrophysics when studying the motion of celestial bodies or in the analysis of projectile motion.
