What is the definition of potential energy of a system?

AI Thread Summary
Potential energy is defined as a property of a system, reflecting the energy stored due to the position of its components relative to each other. In the context of two protons in a helium atom, the potential energy relates to the work needed to bring them together from an infinite distance. This energy is influenced by the electrostatic forces between the protons. Understanding potential energy as a system property clarifies that it encompasses the interactions between all components involved. The discussion emphasizes the importance of recognizing the system's context when evaluating potential energy.

potential energy of a system ?
Relevant Equations
w=DeltaU
hi guys i am encountered with a question that is : two protons in a helium atom stand close together,approximately at a distance of 2 fm. what is the potential energy of this system ?

i can understand the concepts that are potential of a particle or potentail of a object etc but can't understand the potential of a system concept what is the definition of this ? can you explain?

How much work is required to bring those two protons together from infinitely far apart?

That's a bit paradoxical. Potential energy is really a property of a system. When you refer to the potential energy of a rock at the top of a cliff you mean the potential energy of the Earth-rock system.

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...
