Deceleration refers to a decrease in the velocity or speed of an object over a specific period of time. It is the opposite of acceleration, indicating a negative change in velocity. This can occur in various contexts, such as a vehicle slowing down, a moving object encountering resistance, or a celestial body being affected by gravitational forces.In physics, deceleration is quantified as a negative acceleration, where the object’s final velocity is less than its initial velocity. It is crucial in understanding motion, School Management System particularly in scenarios involving braking, drag forces, or gravitational interactions. Deceleration is a fundamental concept in fields like mechanics, transportation, and astrodynamics, influencing the design and operation of vehicles and machinery.
