Systems

Systems

• A collection of particles where the internal interactions do not change, or change very little, or the changes are not relevant to the question can be treated as an object
• Systems have properties that are determined by the properties and interactions of the objects/particles that make up the system and their atomic and/or molecular substructures
• When properties of objects/particles that make up the system are not important in modeling the behaviour of the macroscopic system, the system itself may be referred to as an object
• Protons, Neutrons, and Electrons are known as fundamental particles and, depending on the problem, can be treated as systems or objects
• Electric Charges on Protons, Neutrons, and Electrons arise from their quark compositions
