THURSDAY, NOVEMBER 04, 2010

Today in Physics class, we started off by getting back our Conservation of Energy lab and went through it quickly. Then we were given out 3 worksheets, and reminded to hand in our Power Lab if we have not done so [WHICH IS OVERDUE!] and the lab that we did on Wednesday, regarding the spring and weights [please see previous post to regard about the lab].

The three worksheets provided was the Chapter 11 Transparency 11-1, Chapter 11 Transparency 11-2, and Work and Energy: Springs. We were to complete them so that we could go over them on Friday.

Ms. Kozoriz then gave us the rest of the period to work on our labs and the worksheets.

Have an awesome day (:

Hello Everyone, today we went over the answers of chapter 10 Study Guide page 56 and 57 which are given below;

    

MATCHING:

1. f

2. c

3. a

4. b

5. d

6. e

MCQ'S:

7. a

8. b

9. b

10. a

11. a

12. a

  

For each of the situation shown, write the letter next to the number of the correct expression.

13. B,E,F

14. A,D

15. C

ANSWERS:

16. 30N

17. 0.5m

18. work done

19. 3J

MATCH THE FOLLOWING:

20. a 

21. c

22. e

23. b

24. d

         Those who were absent on Thursday did the lab and the other students were working on chapter 10 Transparency 10-1 (Force, Work and Distance). Ms.Kozoriz helped us solving those questions, the answers are;

1. 150N

2. 8.0m

3. 0-150N as force increases the object moves 3.0m. Between 3-6m a constant of 150N is applied to object. For last 4m force is upward from 150N to 250N.

4. w=f.d

5. w=f.d

w=150N.2m

w=300N.m(J)

          Then Ms.Kzoriz gave us a helpful lecture on Kinetic Energy and Gravitational Potentional Energy. After we performed an experiment on Conservation Of Energy with 3 balls of different sizes and a meterstick. We also get a chapter 11 Transparency11-3 Worksheet in which we have to answer 7 questions.

                      Thats all we did today and also we handed in our lab worksheet on work and power. Unfortunately, tomorrow we dont have a Physics period because its half day. 

                                                                                                              Have a great day,

                                                                                                              Nageena.
