Class 9/2/09

Today we had a double period. During the first period we had our first assessment. In the second period we started the "Engineering a 'Photo Finish" Lab. In class we completed Part A and for homework we have to do Part 2 through question 11. For Part A we were introduced to a new more expensive type of buggy, a car on a ramp. We had to position the ramp so that the buggy and the car reached the end of the ramp at the same times. Then we found the velocity of the buggy and graphed it on a position versus time graph. Next we guessed what the position versus time graph would look like for the car and graphed it on the same axis as the buggy. Finally we used Logger Pro and the motion detector to find more exact data on the velocity of the car. We need that data to complete the homework.
