- 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.
Test Newtons 1st Law
Mr. Crane's Classes
Test Newtons 1st Law
Mr. D's Classes
Is this for honors physics period 9? I wasn't in school so I don't know
ReplyDelete-Patrick
I think its for freshman because we are learning about newton right now.
ReplyDelete~Molly lawlor
Yes, at least period 4, of course.
DeleteThis assignment is for freshman, we talked about it in class
DeleteThe conversion between mass and weight is to multiply by gravity, right?
ReplyDelete-Kevin Meglathery
yeah, Im pretty sure that you have to multiply by 9.8 (the force of gravity) to get the weight
DeleteLarry is right
DeleteThis is due on/by Wednesday, no?
ReplyDeletewhen is this due?
ReplyDelete-Matt Nazha
He said on Friday he was going to make it due Wednesday
Deletehow do you know your "ID"?
ReplyDelete-Robyn
is it student id?
Deleteit is your student number
ReplyDelete16XXXX
Is mr. Crane going to explain this in class? He didn't in period 3
ReplyDeleteI guess we should still do it just in case it was meant for all of his Phresman classes.
DeleteMr. Crane said he will give us an extra day because he didn't tell us about it.
Delete-Skylar Young
I know someone already asked this, but when is it due? I forgot my notebook and want to use it for the test.
ReplyDeleteI 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
DeleteTuesday at midnight

does anyone know how to convert newtons to kgs?
ReplyDeleteI remember something in the packet saying that 10 Newtons was the equivalent of 1 kilogram, if that helps!
DeleteYou can also think of it as dividing by 10 (the acceleration of gravity).
Delete10 N divided by 10=1kg
-Kevin Meglathery
100g is 1 N
Delete100 paper clips
Weight is the force due to gravity
f=ma a=acceleration of gravity.
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.
DeleteYeah that's correct.... so 1 Newton= .1 Kg
ReplyDeleteCarlos
what is free space? does it have friction?
ReplyDeleteFree space probably means that we ignore all possible outside forces like gravity and friction.
Delete-Kevin Meglathery
how do we submit the test?
ReplyDeleteThere is a button in the bottom left corner.
Delete-Kevin Meglathery
are we supposed to show work for the open-ended?
ReplyDelete-Robyn

DeleteWe would if we were in class, so I'm pretty sure we have to show our work for the open ended.
DeleteI submitted my test w/out work for the open ended though b/c I forgot....
Does that mean you put in your conversions in the box?

ReplyDeleteI thoght that mass does not equal weight, yet there are similiar questions to mass equaling weight or vice versa?
ReplyDeletemass doesn't equal weight.
DeleteThey might be asking for the conversion.
Deleteie. How much does "x" kg weigh?
-Kevin Meglathery
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.
Deletewe never learned any of the Aristotle information. What do we do for those?
ReplyDeleteViolent 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
Deletedid anyone find out if this is due tonight ? or is it due wednesday like someone said above ?
ReplyDeleteit's not due tonight
DeleteI believe it is due Wednesday due to the calender at the bottom of the page.
DeleteBy Wednesday means Tuesday at midnight not Wednesday at midnight
Deletewhat is the conversion of mass to weight ?
ReplyDeleteit is in the packet... it is w= mg
Deleteweight= mass X gravity
Weight, not mass, is dependent on gravity, correct?
ReplyDelete-Ciaran
Correct.
Deletewhat is violent motion?- Katie H
DeleteI'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!
DeleteWere did you find out what violent motion is? I can't find anything.
DeleteI 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.
DeleteWhat would be an example of a frictionless space/surface?
ReplyDeleteIce. Technically it's not frictionless, but it's too small to count
DeleteAn 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.
Deletewere we supposed to know the gravitational force on the moon?
ReplyDeleteThis comment has been removed by the author.
DeleteWhat do you mean Aliena? Of course there is gravity in space
DeleteBut 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?
DeleteMr. Crane, should we look up what the conversion is for acceleration from gravity on the earth to the moon?
DeleteI looked it up because I thought we were going to be given it but we weren't, so try looking it up instead.
Deletein 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
DeleteHe told us in his initial blog post on the last bullet:
Delete"Note in the last problem it should read moon's gravity is 1/6 that of Earth."
You should be able to use that 1/6 to find the gravitational force on the moon.

DeleteThe 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!
ReplyDeletesame problem. if you find whats supposed to go in the space, let me know. I looked it up but got multiple answers
DeleteYa, some of the things aren't showing up. And were did you guys find violent motion?
DeleteJohn, 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.
DeleteThe last picture should say 1/6.
Delete-Skylar YOung
What does SI Unit mean?
ReplyDelete---Taylor Nardone (a legend
System International. It's like the standard unit of measurement
DeleteThe SI unit for mass is kg, time is s, weight and force is N
DeleteIt basically means the fundamentals. In this case, it's asking for the fundamental unit of mass.
Deletehow do we submit it? one button says end and the other says clear. does the end button mean end it and submit it?
ReplyDeleteMy 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.
DeleteThere are 2 icons at the bottom left of the screen. Choose the icon on the left. They look similar.
DeleteOn 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?
ReplyDeleteThere's a button at the very bottom that says grade and submit.
ReplyDeletebut there's like two separate buttons and neither one say anything
DeleteI 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
DeleteThanks you!

ReplyDeleteOne 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?
ReplyDeleteNo John, you can have gravity in a vacuum. Space is a vacuum and there is gravity
DeleteYou want to keep it to be the simplest case scenario.
DeleteOk, thanks.
DeleteI hope that hour and a half spent on that test was worth it.
ReplyDeleteAgreed.
DeleteAs long as you put logical reasoning behind your answers, you should be fine.
DeleteWhat is happening with Class Dojo? My blog points have not been updated in forever
ReplyDeleteMr. Crane said the class dojo thing hasn't been working so I think it's fine Noah.

Thank you alexis
DeleteHey, Mr. Crane I didnt mean to submit my quiz to Mr. D because i cliked the worng link just to let you know. Sorry!
ReplyDeleteOnly one test down, two to go!
