What is the definition of potential energy of a system?

Click For Summary
SUMMARY

The potential energy of a system, specifically in the context of two protons in a helium atom, is defined as the energy associated with their position relative to each other. When these protons are approximately 2 femtometers (fm) apart, the potential energy can be calculated using the work-energy principle, represented by the equation w = ΔU. This indicates that the work required to bring the protons together from an infinite distance is equivalent to the change in potential energy of the system.

PREREQUISITES
  • Understanding of potential energy concepts
  • Familiarity with the work-energy principle
  • Basic knowledge of atomic structure, specifically helium
  • Proficiency in using units of measurement such as femtometers (fm)
NEXT STEPS
  • Study the concept of potential energy in multi-particle systems
  • Learn about the forces acting between protons, including electromagnetic force
  • Explore the calculations of potential energy using Coulomb's law
  • Investigate the implications of potential energy in nuclear physics
USEFUL FOR

Students in physics, particularly those studying atomic and nuclear physics, educators teaching potential energy concepts, and anyone interested in the fundamental interactions between particles.

Homework Statement
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?
 
Physics news on Phys.org
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.
