Week 11 Blog, Due Sunday, November 11, 2012
We have been talking about many different forces throughout the week. I would like to know which force(s) and/or concepts are the most confusing for you. If you believe you have mastered all of the types of forces we have talked about and know the concepts equally as well, pick an object or situation and make some observations. Tell me what the object or situation is and then tell me the forces involved, the approximate magnitude of each force, and in which direction each force is acting. Remember, your post must be complete by 11:00 pm on Sunday for full credit. You must make an original comment and comment on at least one other post for full credit. Late posts will be reduced to half credit. If you have any problems or have questions, please let me know by 4:00 pm Sunday. May the force be with you!

Ms. Ego i had many complications at first with figuring out how to find out these forces at first, i was very confused on how to get the net force, air resistance, gravity, etc. But now i am starting to get the hang of things now.
ReplyDeleteMe too crystal. I was completely lost at first with things like the body diagrams. I'm starting to understand things a bit more though.
Deletei have trouble with air resistance and netforce too.
DeleteYes me too! But I think I'm getting the hang of it. :)
DeleteI do too very much!?!
DeleteHonestly I am still having trouble with this, but I am improving. The forces and concepts that are most complicating to me are net force, normal force and application force. I'm working on it though.
ReplyDeletei'm improving to.But i think i still need to work and try a little harder
DeleteI have trouble with the net force too. Getting better as well.
Deletethats easy
DeleteMe too Edward I am also having trouble
DeleteI ahve had trouble with figuring out how to find the force.Sometimes i know automatically but other times i go completely blank. i think i should stay for tutorials one day.
ReplyDeleteMy main problems are the formulas i dont know when to use them or what most of the formulas are
ReplyDeleteyeah me to i get problems wrong because I used a formula wrong and it messes up my entire answer
DeleteYes, I have the same problem. I got the formulas confuse, but I think I'm getting it.
DeleteOne of the problems that I had trouble with was finding the net force of the free body diagrams that has all four forces being applied to the object. Like if you have to add or subrtact the forces or the formula because I forget which one to use for it.
ReplyDeleteYeah I have trouble finding the net force and struggle on choosing what formula to use too.I should show up for tutorials.
DeleteI kinda get confused too. At times i can do it but sometimes I have no idea what formula to use
DeleteOne of the things that I am having trouble with is free body diagrams and how to find the forces on them.The questions on the warm-ups are easy and pretty much it's all common sense, but when it comes to working on them in a worksheet I am clueless as to what to do.I need help finding everything and always ask for help from others so it would be helpful if you went over them more on the board so I won't forget how to do them.
ReplyDeleteFree Body Diagrams! Yes, me too. I honestly think if we get more practice problems our class will do a lot better with these.
DeleteMee too! I don't understand them either.
DeleteThe only thing that I'm confuse with, is identifying the air resistance force because i don't know which direction its going, but overall they seem easy.
ReplyDeleteThe thing i have trouble with is what formulas to use... I usually can work it out with no problem but when there is too many blank spots I tend to get kind of lost
ReplyDeleteThe formulas are easy they are:
DeleteFgrav = mg
Fnet = ma
m=mass
g=9.8
a=acceleration
Yeah i get lost when i see too many blanks as well!
DeleteI feel the same way! If there's too many blanks I get confused on what formulas to use for what.
DeleteSame here!
Deletethe only thing im confused about is normal force
ReplyDeleteThat's not hard at all it's the opposite of gravity. No normal force you would go through the ground.
DeleteI was having trouble with everything but now I think I got it.
ReplyDeleteyup me to i was having a lot of problems with everything i was so confused!
DeleteI have trouble when we have to fill in for the free body diagrams. I get confused as to what to plug in or i simply begin to mix up all the forces. I understand the concept of each but i get lost when i try to solve the problems like on the worksheet.
ReplyDeleteExact same problem with me, i just cant figure it out on problems.
DeleteI get confused with the same thin especially the formulas.
DeleteThe only forces I have trouble with is air resistance and friction. I know what each of them are but sometimes I get confused on when they're being applied.
ReplyDeleteMy post wasn't on here D; but i did another one:D but i agree with your comment i don't know where to apply them.
DeleteThe thing i was having the most trouble with was the Ffric, Fapp, Fair, and Fnorm. I had trouble identifying which went with who and how to find them. After asking my classmates and you MANY questions i got the hang of it. I still think we should get more problems so it can can get easier for us.
ReplyDeleteyea, i still struggle with the Ffric and the Fair. But I'm slowly getting it
DeleteI think Ffric is the most confusing one to me. I wish I could say I'm slowly getting but its not lol
DeleteMs. Ego I know howto find the. Forces when the problem gives you at least the mass or acceleration but without one of those I have trouble figuring it out I guess more problems like that would help alot
ReplyDeleteyeah I'm the same way I only understand it if it gives the mass and acceleration
DeleteI think the most trouble I have with is the net force and normal force. Sometimes I'll understand how to figure it out and other times I just dont understand it.
ReplyDeleteYeah i had problems with that too, but now i finally understand it somewhat.
DeleteMy problem was in using the formulas, but i got it understand it now.
ReplyDeleteMy problem is the free-diagrams and finding the forces. When doing warm-ups they are really easy for me but when i get the worksheet I'm just so confused.
ReplyDeleteYea, same here that happens to me too. I understand it better now though.
DeleteI was extremely confused when it came to using the formulas, but now that I know them it is extremely easy.
ReplyDeleteMy problem is determining the forces. Like applied force and whatnot. I get how to draw free body diagrams though.
ReplyDeleteYes determing whitch force is what whatis also very difficult.
Deletemy problem was just memorizing the formulas
ReplyDeleteFgrav -mg Fnet -ma m-mass g-9.8
a-acceleration
i think the real world applications for what we are learning are a great tool. angry birds may not be real but it's a modern idea!
i had trouble with the formulas 2
Deletethere is a stack of papers on a desk. there is the force of gravity which is moving down and there is a supporting force.
ReplyDeletethis is where my understanding of supporting forces gets blurred. i am confused as to how Fnorm even works.
i kind of have problems with the free diagrams and finding the net forces like in the warmups
ReplyDeleteI've been having trouble with being able to find the forces acting on something by using the other information given, like when all the forces are shown i perfectly understand them and how to get them, but remove a few of them and its like i have never learned any of it in my life.
ReplyDeleteOh i have a problem with this too!! help me ms.ego!!!!!!
DeleteI understand it better now but i'm still a little slow on working on them. I do have trouble on applied force and Fair , but when i have the formulas i get them. I just have trouble remembering the formulas.
ReplyDeleteYou just have to remember that song lol
DeleteI think my only trouble is figuring out the air resistance and friction. I understand everything else pretty well. Honestly, I feel like more practice sheets would help many of us just get a better hang of it.
ReplyDelete-____-dude i thought i had already posted! I think the free body diagrams were hard at first but they are starting to get easy its just i cant remember the formulas and where to apply them.
ReplyDeleteYeah the formulas get me too! :/
DeleteAna Mendoza
I had problems understanding the body diagrams at first.. but i think i'm getting the concept a little bet better now.
ReplyDeleteAna Mendoza
I struggle A Lot with that too
DeleteI dont really know the name of everything but the formulas help me figure out everything i do so its fairly easy. but is the free body diagram the one with the box and arrows? i get that. air ristance gave me trouble though
ReplyDeleteYeah me too
DeleteI'm having some problems with the diagrams but kind of understanding them.Also I think I finally memorized all the formulas.
ReplyDeleteI know how to get the forces & all but idk how to tell the difference between them all. FGrav is the only one I know for sure.
ReplyDeleteI have a lot of troube with the figuring out the equations. I know that Fgrav is equal to Fnorm and that G is 9.8. But it makes me mad that when you do it with is I get it but when I try to do it by myself, I can't do it.
ReplyDeleteMost of the forces are easy to me. Most explain thereselfs like Gravity and Air resistance. The only thing is the body diagram. Other than that its just harder with all the equations. Whitch i
ReplyDeletehave to learn myself.
I kinda sorta get it, but I tend to doubt myself..A LOT!
ReplyDeleteYea same here but not alot
Deletei didn't get the formulas and when to use them but i kind of get it now.
ReplyDeleteWhen we first started I did not understand how to solve or do the problem , I was soooooooo confuse , but now I understand how to do this because I ask for help and question so I'm good now :-)
ReplyDeleteI didn't unerstand it until I used my formulas wrong because I get cinfused but now I understand but I still need some help
ReplyDeleteme to
DeleteMy biggest problem is the net force and I am still having troble but its getting on my mind now
ReplyDeletemy biggest problem is remembering the formulas
ReplyDeletesame here
DeleteThese is my problem as well.
ReplyDeletemy biggest issue is remembering the formulas and net force but im going to get some practice with some problems at the net.
ReplyDeleteI still get confused with the free bidy diagrams, I get confused with the formulas and IT don't understand what probkems they go with.
ReplyDeleteI'm getting the hang of remembering the formulas
ReplyDeleteWhen this was going on I had trouble from time to time with the free body diagrams.
