Please help; Explain phenomena about collision and water.

AI Thread Summary
The discussion centers on understanding the physics of collisions involving water, particularly in a ball. It highlights how the behavior of water changes during successive bounces, with the second bounce not allowing the water to rebound as effectively as the first. The concepts of momentum and energy transfer are mentioned, specifically referencing the equations for conservation of momentum. The interaction between the ball and water affects the height of the bounce due to the timing of the water's movement. Overall, the conversation seeks clarity on the principles governing these phenomena.

Did you have a specific question about this?
 
About motion of collision and water in ball // why object show that ? I not sure about momentum and energy ,i would like more explain.

On the 2nd bounce the water in the ball doesn't get a chance to "bounce" like it did the first time, so it comes crashing down after the ball is already in the air, keeping it from bouncing as high.
 
I explain from Pi = Pf or (m+M)u =(m+M)v, ? not sure
 
Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
