Examples f mdels culd include diagrams, drawings, descriptins, and cmputer simulatins.] PS3.A: Energy is quantitative prperty f a system that depends n the mtin and interactins f matter and radiatin within that system. That there is a single quantity called energy is due t the fact that system s ttal energy is cnserved, even as, within the system, energy is cntinually transferred frm ne bject t anther and between its varius pssible frms. PS3.A: At the macrscpic scale, energy manifests itself in multiple ways, such as in mtin, sund, light, and thermal energy PS3.A: These relatinships are better understd at the micrscpic scale, at which all f the different manifestatins f energy can be mdeled as a cmbinatin f energy assciated with the mtin f particles and energy assciated with the cnfiguratin (relative psitin f the particles). In sme cases the relative psitin energy can be thught f as stred in fields (which mediate interactins between particles). This last cncept includes radiatin, a phenmenn in which energy stred in fields mves acrss space.
