describe the relationship between electrical and magnetic fields. theory describes the behavior of gas in a system. PS3.A and 3.B Definition and conservation of energy and energy transfer [Content found in PS3.D] Moving objects contain energy. The faster the object moves, the more energy it has. Energy can be moved from place to place by moving objects, or through sound, light, or electrical currents. Energy can be converted from one form to another form. Kinetic energy can be distinguished from the various forms of potential energy. Energy changes to and from each type can be tracked through physical or chemical interactions. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter. The total energy within a physical system is conserved. Energy transfer within and between systems can be described and predicted in terms of energy associated with the motion or configuration of particles (objects). In a closed chemical system, the transfer of energy involves enthalpy change and entropy change, though the total energy is conserved. Chemical reactions move toward overall stability, toward a more uniform energy distribution and more stable molecular and network structures. PS3.C Relationship between energy and forces [Content found in PS2.B] When objects collide, contact forces transfer energy so as to change the objects’ motions. When two objects interact in contact or at a distance, each one exerts a force on the other, and these forces can transfer energy between them. Fields contain energy that depends on the arrangement of the objects in the field. N/A PS3.D Energy in chemical processes and everyday life Sunlight warms Earth’s surface. Friction warms objects that rub against each other. Energy can be “produced” or “used” by converting stored energy. Plants capture energy from sunlight, which can later be used as fuel or food. Sunlight is captured by plants and used in a reaction to produce sugar molecules, which can be reversed by burning those molecules to release energy. Photosynthesis is the primary biological means of capturing radiation from the Sun. N/A
