Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models.Īlignment agreement: Thanks for your feedback! Science assumes the universe is a vast single system in which basic laws are consistent.ĭevelop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.ĭevelop and use a model based on evidence to illustrate the relationships between systems or between components of a system.Īlignment agreement: Thanks for your feedback! At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.Īlignment agreement: Thanks for your feedback! These relationships are better understood at the microscopic scale, at which all of the different manifestations of energy can be modeled as a combination of energy associated with the motion of particles and energy associated with the configuration (relative position of the particles). relative positions of charged particles, compression of a spring) and how kinetic energy depends on mass and speed, allow the concept of conservation of energy to be used to predict and describe system behavior.Īlignment agreement: Thanks for your feedback! The availability of energy limits what can occur in any system. That there is a single quantity called energy is due to the fact that a system's total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.Īlignment agreement: Thanks for your feedback! Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system.Īlignment agreement: Thanks for your feedback! Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems.Īlignment agreement: Thanks for your feedback! Mathematical expressions, which quantify how the stored energy in a system depends on its configuration (e.g. This activity focuses on the following Three Dimensional Learning aspects of NGSS:Ĭreate a computational model or simulation of a phenomenon, designed device, process, or system.Īlignment agreement: Thanks for your feedback!Įnergy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system.
