Comparing Beta: Baseball vs Balloon on a Slinky

Click For Summary

Homework Help Overview

The discussion revolves around comparing the damping characteristics, represented by Beta, of a baseball and a balloon placed on a slinky. The participants explore the relationship between mass, damping coefficient, and the spring constant in this context.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants examine the effects of mass and damping coefficient on Beta, questioning how these factors interact. There is uncertainty about which object, the baseball or the balloon, has a greater damping effect and how that relates to their respective masses.

Discussion Status

Some participants have provided insights into the nature of damping and its relation to mass, while others express confusion about the interplay between mass and the damping coefficient. Multiple interpretations of how these factors influence Beta are being explored.

Contextual Notes

There is an ongoing discussion about the definitions and implications of damping in oscillatory systems, as well as the specific characteristics of the baseball and balloon that may affect the damping coefficient.

Homework Statement



Does a baseball on a slinky have a smaller Beta, or balloon on a slinky? Explain.

Homework Equations



Beta = b/sqrt(mk)

b: damping coefficient
m: mass
k: spring constant


The Attempt at a Solution



I see that the spring constant k is the same for either the baseball or the balloon case, because the slinky acts like a spring, so k is the spring constant.

The damping coefficient is different for the 2 cases so is the mass.

Since the mass of the baseball is heavier, it is assumed that the baseball case has a smaller beta. But what about the damping coefficient, b? How will this affect the system? In which case is b larger? I am stuck here on how to relate b, and mass together to get the answer. Thanks for the help.

This may be more of an opinion question than anything else. What causes damping?
 
damping is any effect that tends to reduce the amplitude of oscillations in an oscillatory system

this is also the point that i am confused about, does the mass on the slinky has anything to do with this damping coefficient?

Damping is usually a frictional force. It usually has more to do with size of the object. I think the damping on a balloon is going to be greater, but the mass on the baseball is also greater. It may be an opinion question which wins. That's the problem.
