Although energy cannot be destroyed, it can be converted to less useful forms – for example, to thermal energy in the surrounding environment. (HS-PS3-3), (HS-PS3-4) Solar cells are human-made devices that likewise capture the sun’s energy and produce electrical energy. (secondary to HS-PS4-5) The main way that solar energy is captured and stored on Earth is […]
When two objects interacting through a field change relative position, the energy stored in the field is changed. (HS-PS3-5) source: http://www.nextgenscience.org/
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. (HS-PS3-1) Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems. (HS-PS3-1),(HS-PS3-4) Mathematical expressions, which quantify how the […]
Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that 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 […]
PS3.A: Definitions of Energy PS3.B: Conservation of Energy and Energy Transfer PS3.C: Relationship Between Energy and Forces PS3.D: Energy in Chemical Processes and Everyday Life Students who demonstrate understanding can: HS-PS3-1. Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the […]
