Impulse of Force

力的冲量
The impulse of force is commonly used to calculate forces in collisions.

Active formula
Impulse = Average force x time = mass x change in velocity

Enter data below and then click on the desired quantity in the active formula above.
在下方输入数据,然后点击上方交互式公式中的所需量。

Impulse = FaverageΔt = mΔv

冲量 = F平均 × Δt = mΔv
Impulse
冲量
=N s
Favg
平均力
=N
Δt =s
m=kg
= 千克
中文译文中的待填/计算数值依次对应:1:m。实际数值以上方原输入框为准。
Δv=m/s
Initial velocity
初始速度
vi=m/s
Final velocity
最终速度
vf=m/s

You may change the paramater values and then click on the active text of the quantity you wish to calculate. Values will not be forced to be consistent until you click on the text for some quantity to calculate.
Suggested exercises: explore the effect of initial and final velocities which are of opposite sign (i.e., a collision which reverses the direction of the motion). Note that increasing the time for the collision decreases the average impact force.
您可以更改参数值,然后点击您希望计算的量的活动文本。除非您点击某个量的文本进行计算,否则值不会被强制保持一致。建议练习:探索初始和最终速度符号相反(即碰撞改变运动方向)的效果。请注意,增加碰撞时间会减少平均冲击力。
中文译文中的待填/计算数值依次对应:1:vi 2:vf。实际数值以上方原输入框为准。


Minimizing impact force
减小冲击力
Airplane and duck collision
飞机与鸭子碰撞
Big truck, small truck collision
大卡车与小卡车碰撞
力的冲量常用于计算碰撞中的力。交互式公式 冲量 = 平均力 × 时间 = 质量 × 速度变化
中文译文中的待填/计算数值依次对应:1:imp 2:f 3:dt 4:dv。实际数值以上方原输入框为准。
