Physics

Go over the quiz, discuss answers, problem areas. 

Check and go over the free body diagram homework.

Discuss forces, list examples of everyday forces, newton's three laws of motion.

Demonstration First Law of Motion

HW: Prelab on 2nd Law of Motion. Q's 1-5 on pg. 89.

Physical Science A

Bellwork:
    1.  A group of students are arguing about weight.  The first student explains that weight will stay the     same no matter where you are.  While the second student explains that it will change but can't     remember why.  Which student is correct?  What should student 2 have also included in his     explanation?

    2.  What is the mass of an object that weighs 4500 N on Earth?

    3.  How does pressure relate to forces?

Objectives:
    1.  Explain Newton's Laws of Motion.
    2.  Explain how rockets are propelled through the air.
    3.  Explain how the concept of pressure is useful when explain the effects of an applied force.

Go over and check the pressure problem.

Discuss Newton's Third Law of Motion

HW: Laws of Motion Review Sheet.

Tomorrow we will take a practice test.  This will be a nice review and will provide you with a idea of where you are at with you understanding of the concepts.  You will be able to keep these and use to study.
