The coefficient of restitution

Click For Summary

Discussion Overview

The discussion revolves around the coefficient of restitution (COR), specifically whether the COR of two bodies differs when external forces are applied compared to when they are not. Participants also seek references for further reading on the topic.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions if the coefficients of restitution for two bodies are different when external forces are acting on them.
  • Another participant provides links to external resources for further information on the COR.
  • One participant asserts that the coefficient of restitution is related to impulsive forces between two objects and claims that external forces do not influence it.
  • A later reply supports the idea that the coefficient of restitution remains the same as it is a static value between two materials.

Areas of Agreement / Disagreement

Participants express differing views on whether external forces affect the coefficient of restitution, indicating that the discussion remains unresolved.

Contextual Notes

Some assumptions regarding the nature of external forces and their effects on the COR are not fully explored, and the definitions of terms may vary among participants.

Hello everyone
I learned the coefficient of restitution in school.
I wonder if the coefficients of restitution of two bodies are different in the cases with and without external force acting on the two bodies.
Also, do you guys have any reference paper about COR?
Thank you so much!

The COF is related to implsive forces between two objects and external forces have no influence.
 
As clem was saying the coefficient of restitution will be the same since it's a static value between two materials.
