The coefficient of restitution

AI Thread Summary
The coefficient of restitution (COR) is a static value that characterizes the elastic properties of two colliding bodies, remaining unchanged regardless of external forces acting on them. Discussions indicate that the COR is determined by the materials involved and is not influenced by external factors. Participants shared useful references for further reading on the topic, including Wikipedia and other educational resources. The consensus is that the COR remains consistent between two materials during collisions. Understanding the COR is essential for analyzing impacts in physics and engineering contexts.

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.

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Do electron density waves accompany EM waves in coaxial cables?'

Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
