A 减速计算器 helps scientists, engineers, drivers, and physics students calculate the rate at which an object slows down. Deceleration is an essential concept in physics and engineering, particularly in vehicle braking, motion analysis, and safety studies.
Deceleration is a type of 负加速度, meaning that an object’s velocity decreases over time. This calculator is useful in automotive safety, traffic engineering, sports science, and aerospace applications, where knowing how quickly an object stops is important for 安全高效.
Formula for Deceleration Calculator (w/ formula)
- deceleration formula is derived from the acceleration equation but accounts for a reduction in velocity:
地点：
a = Deceleration (m/s²)
v_f = Final velocity (m/s)
v_i = 初速度（米/秒）
t = Time taken (s)
建立 减速 代表一个 decrease in velocity, the result will be a 负加速度. This negative value indicates the object is slowing down instead of speeding up.
Deceleration Reference Table
To simplify deceleration calculations, the following table provides estimated deceleration values for common scenarios.
| 初始 速度 （M / S） | 最终速度（米/秒） | 时间（秒） | Deceleration (m/s²) | 通用应用 |
|---|---|---|---|---|
| 30 | 0 | 3 | -10.0 | Car braking to a stop |
| 50 | 0 | 5 | -10.0 | Emergency stop at high speed |
| 20 | 5 | 2 | -7.5 | Bicycle slowing down |
| 100 | 0 | 8 | -12.5 | 飞机着陆 |
| 15 | 0 | 3 | -5.0 | Pedestrian running stop |
This table helps estimate deceleration in different real-world applications, making it useful for engineers and students analyzing motion.
Example of Deceleration Calculator (w/ formula)
A car is traveling at 60米/秒 and comes to a complete stop in 6 seconds.
Step 1: Apply the Deceleration Formula
a = (0 - 60) ÷ 6
Step 2: Compute the Result
a = -10 m/s²
这意味着 car is decelerating at a rate of 10 m/s², which is a typical value for a vehicle emergency stop.
最常见的常见问题解答
减速度为 负加速度, meaning that an object is slowing down instead of speeding up. It is measured in 米每秒 平方（米/秒²） and is always represented by a 负值 in equations.
Deceleration is observed in various real-life scenarios, such as vehicles braking, objects rolling to a stop, athletes slowing down, and airplanes landing. Understanding deceleration is important for designing safe transportation systems and sports training programs.
不困难， deceleration is always negative because it represents a decrease in speed. If an object is speeding up, it experiences 正加速度, while slowing down results in 负加速度，称为 减速.
