Physics

Standard PS-6:   The student will demonstrate an understanding of the nature, conservation, and transformation of energy.

 

Indicators

Activities

PS-6.1    Explain how the law of conservation of energy applies to the transformation of various forms of energy (including mechanical energy, electrical energy, chemical energy, light energy, sound energy, and thermal energy).

PS-6.2    Explain the factors that determine potential and kinetic energy and the transformation of one to the other.

PS-6.3    Explain work in terms of the relationship among the force applied to an object, the displacement of the object, and the energy transferred to the object.

PS-6.4    Use the formula W = Fd to solve problems related to work done on an object.

 

PS-6.5    Explain how objects can acquire a static electric charge through friction, induction, and conduction.

PS-6.6    Explain the relationships among voltage, resistance, and current in Ohm’s law.

PS-6.7    Use the formula V = IR to solve problems related to electric circuits.

PS-6.8    Represent an electric circuit by drawing a circuit diagram that includes the symbols for a resistor, switch, and voltage source.

PS-6.9    Compare the functioning of simple series and parallel electrical circuits.

PS-6.10  Compare alternating current (AC) and direct current (DC) in terms of the production of electricity and the direction of current flow.

PS-6.11  Explain the relationship of magnetism to the movement of electric charges in electromagnets, simple motors, and generators.
