February 06, 2009 First thing you did when you walked into class today was go and sit down at your sit. There were no other worksheet that where needed to be picked up today. There was no daily question for today. Once you sat down at your sit, you then you took out the lab worksheet “The Manning-Made Pile Driver Lab: Physics 1” pages 14-15, which we picked up on 2/05/09. Once we took the lab out, we started reading it and making our predictions based on the question. The question was “The average resisting friction force will (a. increase, b. decrease, or c. remain uncharged) as the driving metal cylinder is dropped from a higher position. Then when most where done or finishing up we took a class vote on the prediction that were made. Then Mr. Manning started explaining how to perform the lab. Then we got with our group and started the lab. The general idea of how to do the lab is a nail is started in the block of wood, the guide tube centered vertically over the nail, and the driving cylinder dropped through the tube onto the nail causing it to be driven into the block. One thing you need to find first is the mass of driver so you can use it in an equation later to find the resisting force. You would measure the height of the nail after every drop done with the driving cylinder. Then you would find the nails displacement of the nail, along with the height of the driver. You would drop the driver from the same height twice. After you found all the pieces of information that are needed you plug them into the equation, which is show below. You used this equation to figure out the resisting force. Then we finished up the lab or at least got all the information needed to finish up the lab on our own. Assignments: Homework- Work on Observations/Conclusions: on the page 15, which is on the back of the “The Manning-Made Pile Driver Lab: Physics 1 page 14-15. Also remember to get started working on the Unit 7 Reading Guide: Physics 1.
