Momentum Formula Momentum is a quantity with a value and a direction. It is the product of the mass of an object and its velocity. Momentum is conserved in elastic collisions. The unit of momentum is a kg·m/s, which is also equivalent to a J·s (a Joule·second). momentum = (mass...
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,没有外力施加...

Why is momentum always conserved in elastic and inelastic collisions? What is the equation for the law of conservation of momentum? Is momentum a form of energy? For a particle of mass m and velocity v, what are its momentum, and its (kinetic) energy? Discuss the principles of Conservation...
Why is momentum always conserved in elastic and inelastic collisions? How does mass affect inertia? How Newton's Laws apply to this situation: a mass suspended from two strings? How to draw momentum vectors Is momentum measured in Newtons?
The law of conservation of momentum states that momentum is conserved. This is expressed as (m1)(v1i) + (m2)(v2i) = (m1)(v1f) + (m2)(v2f). So in any elastic collision the momentum is conserved the only change is in the velocity of the two masses. Upvote • 0 Downvote Ad...
Momentum, Collisions, Elastic Collisions, Inelastic Collisions, Completely Inelastic Collision, Impulse, Impulse – Momentum Theorem. The law of conservation of energy is one of the of several great conservation laws in physics. Among the other quantities found to be conserved are the ...
Momentum is conserved,because the total momentum of both objects before and after the collision is the same. However, kinetic energy is not conserved. Some of the kinetic energy is converted into sound, heat, and deformation of the objects. ... In an elastic collision, both momentum and kine...
Momentum is conserved within any system. This means that virtually no momentum is lost in a system once it exists in that system. It also means that momentum cannot be added by objects or agents within the system. The concept of the conservation of momentum explains why external forces are ...
In an isolated system, the momentum of two objects in a collision is conserved. In other words, combined momentum before and after a collision of two objects in motion remains the same. Momentum is not destroyed but transferred between the two colliding objects. ...
