Many time people who knows almost everything and people who knows few and are confused by formalities and misconception ,have the same answers.
Is it a coincidenve or phenomenom of modern scientist who needs to finish all their...

THE SAME WAGONS IMPACTED ELASTIC, AFTER THE COLLISION A LOCK CONJOINT THEM.
ALL THE MOLECULES OF THE WAGONS HAVE SPEED 5(AFTER COLLISION-..).WE SIGNIFY A LOSS OF ENERGY SAYING THAT...
but we cannot separate the system.the system consists from the bullet and container .they have the quantums.And we want to examine exactly how the energy and momentum exists on it.Of course it is easily for us when the object is like a wooden pendulum which harmed by a bullet(complicated...

We have a container and a bullet (of the same mass for easiness)
bullet is inside and has a speed from left to right.when it impacts to the right wall of the container ,it stops and the container now move.because practically we can not...
Energy and momentum.The misunderstanding has prevailed
Two train wagons of the same mass will impact.
Wagon A has velocity 10 and wagon B 0.When they impact a lock will make them conjoint.
Which will be the velocity of two wagons and which the energy after the collision;
We use the...
