AI Thread Summary

The discussion emphasizes that the classical kinetic energy formula (mv^2/2) is only valid at low speeds and serves as an approximation. For high-speed scenarios, particularly when dealing with relativistic effects, the exact expressions for energy and momentum must be utilized. Participants highlight the limitations of approximations in physics and the importance of applying the correct formulas based on the speed of the object. Understanding these distinctions is crucial for accurately calculating the relativistic energy and momentum of a proton. Accurate calculations are essential in advanced physics contexts.

I see you are aware that mv^2/2 is only an approximation. As a general rule of thumb, any approximation will have some limited domain of usefulness. In this case, it is only an approximation at low speeds. For high speeds you should use the exact expression.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
