Author Michael Poland Monday 11/24/08 Physics 5th Period Homework buy a protractor and ruler by Wednesday 12/3 As we walked into class we picked up several beginning of the unit papers. Following that we got back papers including the Force of Friction lab and the unit test. We then proceeded to go over the test. This upcoming unit will be very short. After that attention was moved to the papers we had just pickup up. On page 2 we made predictions for what would happen. Mr. Manning then demonstrated a demo that corresponded with page two. We then wrote down our observations. Mr. Manning collided two force sensors together. Before each demo he surveyed members of the class to hear their predictions. The scales were modified for different experiments by changing mass and the velocity. Contrary to many of our predictions all answers from 1-9 were equal force. When mass was added to one scale with an equal velocity the force was surprising still the same for both. For the last demo the friction was changed for one scale. The test was inconclusive because it yielded no clear result. After the demos we completed the conclusions. In the picture below Mr. Manning is attempting to cast a physics spell.
