Email Info

If you need to reach me for any reason, you may contact me at lisa.robak@edison.k12.nj.us.
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

Forces act on you and everything around you at all times. Any time an object stops moving, starts moving, or changes direction, it does so because a net force is acting on it.  Newton's Laws describe how force affects velocity. Most objects experience forces in more than one dimension. The amount of friction determines how much force is needed to move an object.


THIS WEEK (11/16 - 11/23):

This week we will begin to take a look into Newton's 3 Laws of Motion. We will understand how forces cause objects to move or not move at all. We will also look further into Newton's Second Law of Motion and use it to compute the amount of force needed to accelerate an object. We will distinguish between weight and mass, as well as understanding the nature of frictional forces and how they affect the motion of an object. At the end of the week, we will take our first look at Free Body Diagrams (FBD's) and identify all the forces and accelerations associated with them.

 

NEXT WEEK (11/28 - 12/2):

This week we will continue to study Free Body Diagrams (FBD's). It will be understood that if an object is moving with a constant velocity, the applied force and frictional force are equal but opposite to each other - which will be applied to FBD's. Drawing a diagram to indicate all the forces acting on an object is vital to understanding its motion. We will continue to identify all the forces acting on an object and determine if the object will accelerate, but now we will be analyzing situations where objects have more than one applied force and objects are on an inclined surface.
