DE.3. Energy and Its Effects
3.1. The Forms and Sources of Energy
Enduring Understanding: Energy takes many forms. These forms can be grouped into types of energy that are associated with the motion of mass (kinetic energy), and types of energy associated with the position of mass and with energy fields (potential energy).
3.1.B. The energy of a moving object depends on its speed. Faster moving objects have more energy than slower moving objects. (Level: Essential)
3.2. Forces and the Transfer of Energy
Enduring Understanding: Changes take place because of the transfer of energy. Energy is transferred to matter through the action of forces. Different forces are responsible for the transfer of the different forms of energy.
3.2.A. Force is any push or pull exerted by one object on another. Some forces (e.g., magnetic forces and gravity) can make things move without touching them. (Level: Essential)
