(5) Science concepts. The student knows the nature of forces in the physical world. The student is expected to:

• (A) describe the concepts of gravitational, electromagnetic, weak nuclear, and strong nuclear forces; 
• (B) describe and calculate how the magnitude of the gravitational force between two objects depends on their masses and the distance between their centers; 
• (C) describe and calculate how the magnitude of the electric force between two objects depends on their charges and the distance between their centers ; 
• (D) identify and describe examples of electric and magnetic forces and fields in everyday life such as generators, motors, and transformers ; 
• (E) characterize materials as conductors or insulators based on their electric properties; and
• (F) investigate and calculate current through, potential difference across, resistance of, and power used by electric circuit elements connected in both series and parallel combinations .
