I was wondering if i can use the virial theorem for a potential of the form

V(x)=A*|x|

Got some trouble at the point x=0.

Best regards

In summary, the virial theorem is a useful tool in physics, but at the point x=0, where the potential is not well-defined, it may cause some trouble. It is best to avoid using the virial theorem at this point and consider alternatives such as using a different potential function or limiting the application to a small neighborhood around x=0. Best of luck with your research.

Hello there,

Thank you for your question. The virial theorem is a useful tool in physics for understanding the behavior of systems with a potential energy function. In general, the virial theorem states that the average kinetic energy of a system is related to the potential energy by a factor of -1/2.

In the case of a potential of the form V(x) = A*|x|, the virial theorem can still be applied. However, at the point x=0, there may be some trouble as you have mentioned. This is because the potential is not well-defined at this point, since it is undefined for x=0. In this case, it would be best to avoid using the virial theorem at x=0.

One possible solution is to consider a small neighborhood around x=0 and use the virial theorem for that region. This would give you an approximate value for the kinetic energy at x=0. Alternatively, you could also consider a different potential function that is well-defined at x=0, such as V(x) = A*x^2, and then apply the virial theorem.

I hope this helps. Best of luck with your research.

Best regards,
