Freshman Physics not as easy as pie

Post ideas questions here.

Do not draw your BLOF. JUST THE POINTS

13 comments:

  1. Should the curved BLOF on Tuesday's homework go through all the points? Or is it like a straight BLOF that goes through most of them?

  2. Mr. Crane, you didn't print enough graph paper in class so I'm using my own. The squares aren't as small as the ones in class, but they aren't that big. There's my intuition right there.

  3. Kevin Meglathery,
    I saw your question and though i could help. A BLOF, as you know, is a best line of fit. In my class, Mr. Crane said it should go through as many points as possible and be straight. If the number of points are equal on both sides, then it is a BLOF. Hope this helps!

  4. Hi Mr. Crane!
    The points are good and the data is labeled, I now have an idea of where the BLOF is.

  5. Weighing in a BLOF is a line that goes through as many points as possible. it May be straight or not, it depends on the data... One way to test is that a straight line will be straight no matter what the scale. if your graph changes when you change the scale then it probably is not linear.
    Example: The Earth is flat! Don't believe me? Look outside. Now look at it from space. It's different. Linear things will always look linear. Non linear things may look linear due to the scale under which they are being viewed. See the Earth.

  6. I never got graph paper, is there a place I can print it out online?

  7. For the chart we had to fill out for homework, for the very first one if we have like 14 for period and 5 for length then what do we put for change in period and change in length since its the first one ?

  8. I believe they should be zero considering there is nothing above it. But check with him to make sure.

  9. I wasn`t in class today, was what the first changes should be ?

  10. Bree, I think the change should be zero. Since 5 is your first measurement, then you do not have a measurement before that to subtract it from to find the change.

  11. Mr. Crane, our class didn't have you today and you said you would post something to finish up the Not As Easy As Pie Lab lesson. Do you just want us to graph those points that you posted now, then?

  12. I know this is rather off topic, but one of the entries was talking about the earth and the angle at which it is looked at. I was wondering if any one saw the moon on Thursday, when it was orange, giant, and close to the horizon. I know that it is orange because the light has to pass throught more of the atmosphere, but does anyone know what that type of moon is called?

  13. For the homework due tomorrow with the graphing the first 5 points, are we going to have to graph the other ones on the same graphs at some point? I just want to know how to scale them.
