Discussion Overview

The discussion centers on the factors influencing whether a heavy object will bounce when dropped from a certain height. Participants explore the relationship between weight, material properties, and other variables affecting bouncing behavior, including elasticity and surface area.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the weight required for an object to not bounce, suggesting it may be proportional to the height from which it is dropped and other variables.
  • Another participant argues that the elasticity of the materials involved is more critical than the object's weight in determining whether it will bounce.
  • A different participant introduces the square-cube law, explaining that as an object increases in size, its volume grows faster than its surface area, potentially affecting its bouncing behavior.
  • This participant also speculates on the impact of a large rubber ball, suggesting that a massive object might not bounce due to the shockwave generated upon impact, which could cause structural failure.
  • Another participant expresses curiosity about the relationship between density and bouncing, questioning whether it relates to the square-cube law and the effects of shockwaves on atomic structures.

Areas of Agreement / Disagreement

Participants present multiple competing views regarding the factors that influence whether an object bounces, with no consensus reached on the primary determinants.

Contextual Notes

Participants discuss various assumptions about weight, elasticity, and material properties without resolving how these factors interrelate or the specific conditions under which an object may or may not bounce.

How heavy does an object have to be so that it won't bounce when dropped from some height h (I'm guessing it's proportional to h as well as other variables)?

Is the reaction force from the floor what destabilizes it and causes it to bounce? How does the surface area that comes in contact with the floor play a role? What other variables need to be considered?

THanks

It's not about the weight, but the elasticity of the materials involved.
 
I'm assuming that when you say heavier its because its getting bigger, if so then you need to read up on is something called "the square cube law" Basically as something in increases in size its volume increases faster than its surface area and because the scaled up model is made of the same tiny atoms its overall properties change.

If you made a giant one mile radius rubber ball and dropped it on Earth its not going to bounce, chances are the shockwave of the impact would tear it apart. It would most likely look like dropping an egg.
 
Mmmm, I guess that or it gets denser...

Why is that? Does that have to do with the square cube law you mentioned (I'm about to look it up?). I feel like asking how the shockwaves would tear it apart (basically knocking atoms?) and if it's sound and stuff but I already have another thread going on about sound waves and shock waves lol
