Elastic collision 的表现主要为两个物体在碰撞后立即向相反的方向弹开;inelastic collision一般表现为两个物体在碰撞后往一个方向继续运动,其中在完全非弹性碰撞(perfectly inelastic collision)的情况下,两个物体会粘着彼此往一个方向移动。 不论是哪种类型的碰撞,由于物体在碰撞的过程中只有物体的相互作用,没有外力施...
也就是说,当你从高台跳到平地上时,如果你的双腿在一瞬间直接落在坚硬的地面上,地面对你施力的时间极短,你的腿受到的力和冲击是巨大的(想想就觉得很疼有木有!)。 但如果你跳下来后选择在地上滚来滚去,或者选择作弊用降落伞着陆,都可以延长(地面对你的腿施加的)力的作用时间,在同样的impulse下,你的腿受到...
When two billiard balls collide, in which direction would they travel after the collision? If a meteorite hits the earth, why does the earth remain in its orbit? When two cars collide with each other, why is one of the cars more damaged than the other? We will find that to answer ...

impulse forcefulness, strength, force - physical energy or intensity; "he hit with all the force he could muster"; "it was destroyed by the strength of the gale"; "a government has not the vitality and forcefulness of a living man" 2. momentum - the product of a body's mass and its...
This impulse acts upon the object to change its velocity and thus its momentum. h. TRUE - Yes!!! This is the impulse-momentum change theorem. The impulse encountered by an object in a collision causes and is equal to the momentum change experienced by that object. i. TRUE - A force ...
unit of impulse is N s or kg m s1. If the force acts on the object is not constant then Since impulse and momentum are both vector quantities, then it is often easiest to use them in component form : where consider 2-D collision only 6 When two objects in collision, the ...
Using the definition of impulse, the change in momentum of car 1 is given by Δp1 = F1Δt, where F1 is the force on car 1 due to car 2, and Δt is the time the force acts (the duration of the collision). Intuitively, it seems obvious that the collision time is the same for ...

Impulse, that has been applied to an object, is seen to yield an original vector change in its direct impulse, also in the attendant direction. The SI unit of impulse is the Newton second (Ns), and the dimensionally original unit of impulse is the kilogram cadence per second (kg ⋅ m...
