Physical Science A:

Bellwork
    1.  What is the weight of an 880 N object?
   
    2.  How much pressure is being exerted by a 400 N object that has an area of contact of .8m2?

    3.  Explain the motion of a rocket using Newton's Third Law.


Objectives:
    -Review all the concepts discussed in class.

Go over the homework.  Check and discuss.

Practice Test.  Focus on good test taking skills, reading carefully, and relaxing.

When finished, study for the test.






Physics

Bellwork:
    1.  Draw a free body diagram of a situation where a person pulls on a box with a rope causing the box     to move with a constant acceleration.  Is there a net force acting on the object?  If so, what is     producing the net force?


Go over and check the prelab.

Discuss forces, free body diagrams, and newton's second law.

Explain the Second Law Lab. 

HW: pg 93, 95, 98,100, 101 (q's 6-21)
