If you did not do the vector homework or the pillbug race calculation homework. Then do it tonight for homework.

Wednesday, September 25, 2013

for Thursday in class

Bring in your data table with the velocities of each segment calculated. Show the formula and the calculations. Also bring in the vector homework rewrite.

Tuesday homework

The data from the pillbug race needs to be analyzed segment by segment. Use the pt slope formula. change of Y divided by the change of X. Do it for your pillbug race data(all the data, not just the fastest). Remember if yours runs backwards you will get a negative number which changes your direction. Calculate all the velocities, remembering to show the direction and the magnitude (number and unit in cm/s).

Most people did the homework incorrectly. Although the math is really simple, the diagram must be drawn and labeled exactly, so that the situation makes sense to someone. The resultant vector is shown when properly done and lays beside the original vector drawing. You must also show the math along with the direction. Place the big number over the small number. the bigger number gets the direction in the resultant vector. These are easy questions on the Physics MCAS. But the process of setting up a diagram is what they are looking for. You must always show your work. Good luck, please redo the homework and follow the steps correctly.

Thursday hw physics

Do the vector and free body diagram homework found in the student resources on the blog. It is four problems. Look at the example and make sure to draw the vectors that describe the motions, then the resultant vector, Show the math for addition or subtraction, and make sure all three vectors for each question are labeled with number, units and direction. this is graded hw. Please do it on a separate piece of paper and hand it in tomorrow. Do not email it.

Many students had trouble with the quiz. It was modeled after the worksheet we gave in class. Please review this material if you had trouble with the quiz. Don't forget the work for mr. Hennessy listed on his blog.

Quiz tomorrow on the terms of scientific method and experimentation and the selected vocabulary from chapter 1.

If you were absent you can take notes from chapter 1 section 1 and 2. We forgot to put hypothesis in the scientific method between research and testing by doing and experiment. It would help if you knew the steps of the Scientific method and these vocabulary words: hypothesis, theory, law, controlled experiment, variable group, control group, science, physics.
