Newton's Laws Tests

  • You may use your notes to complete the test it should be done in one attempt.
  • You may discuss concepts but not questions on the tests.
    • Ex. How do you do # 3? (Bad)
    • Ex. What are the units of mass and weight? ( good)
  • Click on the link below to start.

  • Note in the last problem it should read moon's gravity is 1/6 that of Earth.

  1. Is this for honors physics period 9? I wasn't in school so I don't know

  2. I think its for freshman because we are learning about newton right now.

    1. Yes, at least period 4, of course.

    2. This assignment is for freshman, we talked about it in class

  3. The conversion between mass and weight is to multiply by gravity, right?

    1. yeah, Im pretty sure that you have to multiply by 9.8 (the force of gravity) to get the weight

  6. Is mr. Crane going to explain this in class? He didn't in period 3

    1. I guess we should still do it just in case it was meant for all of his Phresman classes.

    2. Mr. Crane said he will give us an extra day because he didn't tell us about it.

  7. I know someone already asked this, but when is it due? I forgot my notebook and want to use it for the test.

    1. I can't imagine that he'd give you only one night considering it's a computer assignment. He told our class Wednesday so I'm gonna go with that

    2. Tuesday at midnight

  8. does anyone know how to convert newtons to kgs?

    ReplyDelete
    Replies
    1. I remember something in the packet saying that 10 Newtons was the equivalent of 1 kilogram, if that helps!

      Delete
    2. You can also think of it as dividing by 10 (the acceleration of gravity).

      10 N divided by 10=1kg
      -Kevin Meglathery

      Delete
    3. 100g is 1 N
      100 paper clips
      Weight is the force due to gravity
      f=ma a=acceleration of gravity.

      Delete
    4. Instead of looking at it proportionally like multiplying and dividing by .1 as needed, isn't it better to use the F=ma formula? That way you plug in acceleration of gravity and whatever value they gave you.

      Delete
  9. Yeah that's correct.... so 1 Newton= .1 Kg

  10. what is free space? does it have friction?

    ReplyDelete
    Replies
    1. Free space probably means that we ignore all possible outside forces like gravity and friction.

  11. how do we submit the test?

    2. We would if we were in class, so I'm pretty sure we have to show our work for the open ended.

      I submitted my test w/out work for the open ended though b/c I forgot....

    3. Does that mean you put in your conversions in the box?

  14. I thoght that mass does not equal weight, yet there are similiar questions to mass equaling weight or vice versa?

    ReplyDelete
    Replies
    1. They might be asking for the conversion.
      ie. How much does "x" kg weigh?
      -Kevin Meglathery

      Delete
    2. Weight is related to mass, but not vice versa because mass is a fundamental of physics. Weight is directly dependent to, and varies upon, gravity, while mass will always be the same, regardless of where you are.

  15. we never learned any of the Aristotle information. What do we do for those?

    1. Violent motion is applied and would not occur normally. Normal motion occurs without having to do anything to it. A book falling off a bridge is normal and throwing a book off a bridge is violent

  16. did anyone find out if this is due tonight ? or is it due wednesday like someone said above ?

    ReplyDelete
    Replies
    1. I believe it is due Wednesday due to the calender at the bottom of the page.

    2. By Wednesday means Tuesday at midnight not Wednesday at midnight

  17. what is the conversion of mass to weight ?

    ReplyDelete
    Replies
    1. it is in the packet... it is w= mg
      weight= mass X gravity

  18. Weight, not mass, is dependent on gravity, correct?

    1. what is violent motion?- Katie H

      Delete
    2. I'm pretty sure that violent motion is anything that natural motion isn't. For example throwing a rock in the air would be violent because its working against gravity, but when the rock starts to fall it becomes natural since its moving with gravity. I think that's what they mean, but I would double check!

      Delete
    3. Were did you find out what violent motion is? I can't find anything.

      Delete
    4. I found out what violent motion was briefly from the Newton's Dark Secrets video. It's basically anything that happens by an outside force, like lifting up a rock.

      Delete
  19. What would be an example of a frictionless space/surface?

    ReplyDelete
    Replies
    1. Ice. Technically it's not frictionless, but it's too small to count

      Delete
    2. An example would be an ice skating rink, when you slide a puck on the ice it will keep going until another outside force acts on it.

  20. were we supposed to know the gravitational force on the moon?

    2. What do you mean Aliena? Of course there is gravity in space

      Delete
    3. But Nick, we may have a similar problem. On the final question of the quiz, it says that acceleration due to gravity is something that on earth. The something is a rectangle that looks like an image that failed to load. I don't know what to do now. If the image showed up on anybody's computer, can you tell me what it says?

      Delete
    4. Mr. Crane, should we look up what the conversion is for acceleration from gravity on the earth to the moon?

      Delete
    5. I looked it up because I thought we were going to be given it but we weren't, so try looking it up instead.

      Delete
    6. in IE it says it is 1/6. Use IE instead of chrome or safari or firefox or whatever because the images and buttons show up

      Delete
    7. He told us in his initial blog post on the last bullet:

      "Note in the last problem it should read moon's gravity is 1/6 that of Earth."

      Delete
    8. You should be able to use that 1/6 to find the gravitational force on the moon.

  21. The pictures are not showing up on my browser! I don't know what the picture is in the last question and I don't know what the 2 buttons at the bottom are! Help!

    1. same problem. if you find whats supposed to go in the space, let me know. I looked it up but got multiple answers

      Delete
    2. Ya, some of the things aren't showing up. And were did you guys find violent motion?

      Delete
    3. John, I did a quick google search and found that natural motion is a motion that occurs naturally such as a book falling or the sun rising. But a violent force is applied like throwing or picking up a book.

      Delete
    4. The last picture should say 1/6.

    1. System International. It's like the standard unit of measurement

    2. The SI unit for mass is kg, time is s, weight and force is N

      Delete
    3. It basically means the fundamentals. In this case, it's asking for the fundamental unit of mass.

  23. how do we submit it? one button says end and the other says clear. does the end button mean end it and submit it?

    ReplyDelete
    Replies
    1. My buttons didn't have any writing in them, so whichever one is on the left side, that's the one you hit to submit it.

      Delete
    2. There are 2 icons at the bottom left of the screen. Choose the icon on the left. They look similar.

      Delete
  24. On my screen, there's two things at the bottom but they're little symbols telling me they can't load. Can someone who can see them tell me which one is the submit button?

    ReplyDelete
  25. There's a button at the very bottom that says grade and submit.

    1. but there's like two separate buttons and neither one say anything

      Delete
    2. I opened up my IE browser instead of chrome. Moon's gravity is 1/6 that of earth. The button on the bottom left is grade and submit and the bottom left is refresh and clear

  27. One of the questions seems like it could be mutliple answers. For #8, an object in a vaccum would also have no forces, wouldn't it?

    1. No John, you can have gravity in a vacuum. Space is a vacuum and there is gravity

    2. You want to keep it to be the simplest case scenario.

  28. I hope that hour and a half spent on that test was worth it.
