A 減速計算機 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 負の加速度, 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 安全性と効率.
Formula for Deceleration Calculator (w/ formula)
この deceleration formula is derived from the acceleration equation but accounts for a reduction in velocity:
どこ：
a = Deceleration (m/s²)
v_f = Final velocity (m/s)
v_i = Initial velocity (m/s)
t = Time taken (s)
Since 減速 〜を表す decrease in velocity, the result will be a 負の加速度. 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.
| 初期 速度 （M / S） | 最終速度（m/s） | 時間（秒） | Deceleration (m/s²) | 共通アプリケーション |
|---|---|---|---|---|
| 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 | 飛行機の着陸 |
| 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 m / s 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
これはつまり car is decelerating at a rate of 10 m/s², which is a typical value for a vehicle emergency stop.
最も一般的な FAQ
Deceleration is 負の加速度, meaning that an object is slowing down instead of speeding up. It is measured in メートル/秒 二乗 (m/s²) and is always represented by a 負の値 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.
いいえ、 deceleration is always negative because it represents a decrease in speed. If an object is speeding up, it experiences positive acceleration, while slowing down results in 負の加速度、と呼ばれます 減速.
