         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.
