AI Thread Summary
Calculating the energy or velocity of a shockwave required to collapse a mass, such as 5 kg, depends on the material properties and the definition of "collapse." Different materials, like sponges and rocks, require varying amounts of energy for compression. The extent of collapse must also be specified, whether it is a minor volume reduction or a complete compression to atomic scales. Without clear definitions and parameters, accurate calculations cannot be made. Understanding these factors is essential for any meaningful analysis of shockwave effects on mass.

Is it possible to calculate the energy or velocity of a shock-wave needed to collapse a mass of, let's say 5kg.

Not from the description of the problem as you've given it. It will take a lot less energy to compress a sponge than a rock. Also, you need to define what you mean by collapse. 5% contraction of volume? Compressed to the size of a proton? Etc.
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
