If for any reason you will be absent from class and know in advance, please notify me by email so that I can ensure you receive the work that you need in order to stay with the class.

Extra Help

Extra Help is available in the mornings at 7 AM. Extra help is available after school if you give me notice in advance. Please make sure you come prepared with questions so that the time can be used efficiently.

Grades

Please check your grades on a weekly basis -  if you have any missing grades or an ABS in place of a grade for an assignment, you must show me the assignment or make it up ASAP before it gets changed to a zero grade as per class policy.

Physics News

 Electrostatics is the study of electric charges that can be collected and held in one place. The effects of electrostatics are observable over a vast scale, from huge displays of lightning to the submicroscopic world of atoms and molecules. Electric charge is not created or destroyed, it is conserved. Charging is the separation, not creation, of electric charges.
THIS WEEK (3/21 - 3/25):

This week we will begin to take a look at electrostatics. We will learn that there are two kinds of electric charge, positive and negative. Like charges repel and unlike attract. We will discuss how objects can be charged by the transfer of electrons. When studying insulators and conductors, we will see that charges added to one part of an insulator remain at that part, and charges added to a conductor quickly spread over the surface of the object.

 

 

NEXT WEEK (4/4 - 4/8):

This week we will continue to explore electrostatics, particularly how to charge an object. Objects can be charged two ways, by conduction (by touching a neutral object with a charged object) and by induction (a charged object is brought near a neutral object and the charges separate). We will use Coulomb's Law to determine the force between two charges, which depends on the charge itself and the distance between the charges. The SI unit for charge is the Coulomb (C).  Grounding is used to remove excess charge by touching an object to Earth.
