Physical Science A

Bellwork:
    1.  Explain what work means in science. 

    2.  How does the meaning of work in science differ from that of work in the real world?

Objectives:
    1. Compare work done in different situations.  Give two examples of work being done and   
            compare the magnitude of the work in each situation. 

    2. Explain why work has a more precise scientific meaning than the meaning of work in everyday     language.

    3. Calculate the amount of work done on an object that is moved from one position to another.      Use the formula W=Fd to solve for the work done by an object.

Hand in and check the Test Rememdiations and the Vocabulary.

Discuss Work and Power.

Go over the math problem for work and power.

HW: Work and Power Problems

Physics:

Bellwork:
    1.  Answer the force question on the white board

Hand in and discuss the rocket explanation. 

Test the predictions:  1/3 water
               1/2 water
               3/4 water

Check and go over the the math problems. 

Pick-up a prelab and lets discuss forces and angles.

Discuss Lab method and begin lab today, we will finish lab tomorrow. 

HW:2-Dimensional Forces lab(do as much of the lab that you can).  Pick-up the friction and statics problems, if you would like to get started, you could work on the statics problems.  We will begin those tomorrow.
