Please help; Explain phenomena about collision and water.

Click For Summary

Discussion Overview

The discussion revolves around the phenomena of collision and the behavior of water within a ball during such events. Participants explore concepts related to momentum, energy, and the dynamics of bouncing objects.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant seeks clarification on the motion of collision and the behavior of water in a ball, expressing uncertainty about momentum and energy concepts.
  • Another participant suggests that during the second bounce, the water does not have the opportunity to "bounce" as it did during the first, which affects the height of the bounce.
  • A different participant attempts to explain the situation using the principle of conservation of momentum, referencing equations related to initial and final momentum, but expresses uncertainty about the application.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants expressing different viewpoints and uncertainties regarding the mechanics of collision and the behavior of water in the context described.

Contextual Notes

Participants have not fully clarified their assumptions regarding the system's dynamics, and there is a lack of consensus on the application of momentum and energy principles in this scenario.

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
