AI Thread Summary
When a stretched spring begins to pull a mass back towards its equilibrium point, the work done by the spring is considered positive. This is because the spring exerts a force in the direction of the mass's movement, which is towards the equilibrium position. The potential energy stored in the spring is converted into kinetic energy as the mass moves. Understanding this concept is crucial for analyzing systems involving springs and masses in physics. The discussion emphasizes the relationship between force direction and work in mechanical systems.

Hi,

I am thinking about a stretched spring with a mass on it. When the spring is fully extended and has just started to pull the mass back towards the equilibrium point, is the work positive or negative?

I think as the spring is pulling the mass then work is positive but I'm not sure. Thanks!

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...
