1. ### K.E. and momentum

...proportional to momentum? No Why in collisions total momentum is conserved....) or vise versa. In fact in calculation of collisions , either momentum or energy conservation can be...

2. ### momentum(about elastic collision and inelastic collision )

...will be minimum. Conversely, if the 2 objects stick together after the collision , the loss in K.E. is maximum, because this is the only possible situation...

3. ### momentum and K.E.

... with elastic collision and inelastic collision . In elastic collision ,the kinetic enery is ... 2 answer in K.E. formula. In inelastic collision case, you will find that both answers...

4. ### momentum(about elastic collision and inelastic collision )

...you are asking how to let the initial and final kinetic energy be equal. In an elastic collision , we can use a air track so that the friction is highly reduced . ...

5. ### conservation of momentum

a. In a collision , momentum is conserved when there is no..., the velocity of A relative to B before the collision is 4.21 m/s in the direction of N61.6*W. ii. As the collision ...

6. ### Collisions

elastic collision : collision in which there is no loss of kinetic energy of the system. inelastic collision : collision ... collision : process in which the collided objects stick together after the collision . Note that in all three collision processes, momentum of the system is always ...

7. ### 彈性碰撞,非彈性碰撞,爆炸既物理力學題點做?

...formula for specific situations. The most important concepts in collision are: 1. law of conservation of momentum(動量守衡) 2. law of conservation of kinetic...

10. ### photon-atom collision (to天同)

... more commonly called "excitation". The term "inelastic collision " is usually applied to the process of Comption Scattering. If a high energy photon ( in the x- or gamma ray range) collides with an atom, it may knock off an orbital...
