Physical Science A

Bellwork:
    1.  What is energy?  How does it work?  Where does it come from?  How can we use it?


Test Remediation Day.  Pick up you test remediation, answer only the questions that correspond with the questions that you missed on the test.

Also, get your binder in order.  I will check them today.

HW:  Vocabulary due tomorrow along with the test remediation.  If you have not read the chapter be sure to do so and begin taking notes on the material!  This will help with the note taking process and also provide you with more time to process and ask questions in class while we discuss.

Physics

Bellwork:
    1.  Ian and Dave pull on ropes attached to a box.  Ian pulls to the left with a force of 45 N.  Dave pulls     in the opposite direction.  If the box which has a mass of 120 kg, accelerates at a rate of .9 m/s2     towards Dave.  How large was the force that Dave applied.

    2.  If an object has a weight of 450 N acting on it and it is at rest on a horizontal surface, what is the     magnitude of the normal force acting on it?

Collect Lab/Check the book work.  Go over questions of concern.

Continue discussing Newton's Third Law and Friction

Explain the fan and cart/also the rocket launch

Explain the process for the 2nd law problems, friction, and begin statics.

HW:  2nd Law Problems and Statics.
