Free Body Diagrams

Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.

Man I love the Portal series. It really tests your mind and problem solving skills.

[@NedjieSalomon]

Thank you. So much. My physics teacher doesn't explain this at all, she just "expects" us to know how to do it. This really helps.

[@tristandepew8972]

Thank you so much for making these videos! They help so much!

[@Thorang]

Thank you so much!! I am so relieved to have found this video. My teacher just told us to learn it on our own and I was so confused! This made it make sense!!

[@babeepopbri95]

You have no idea how much this helped. Thank you so much. I hope you keep posting videos because I have another 5 months of physics!

[@areumc5820]

Best science teacher ever!

[@geetamohammed8182]

Thanks Mr. Andersen

[@mnorberta24]

This was really helpful, thank you very much!

[@dialasaab972]

i literary did the smarty pants dance after i understood this lesson , i have a test on monday and didn't think ill ever be able to pass , so i'll pass all thanks to you!

[@yumpatMEOW]

Portal :D! Thanks for the detailed explanation on these various examples.

[@The300Spartis]

the multiple examples really helped

[@cluecollector007]

Thank you! This really helped a lot :)

[@alifiyahh6387]

Thank you, that was really helpful

[@sachinjanky398]

Thank you !

[@ISLAMguidanceful]

in the case of the box being pulled by a rope why isnt there a tension force?

[@paramrajeshirke26]

Thanks a lot!

[@letoast7480]

thanks really helped!

[@im2awesome2die]

Thanks!

[@RyanThompsonSolU]

Good video. I like how you picked different situations for the Normal force. Do you mind if I link to your video from my site?

[@richardparker123]

THANKS!

[@91Sannie]

u are awesome!!!!!

[@jemappellelanoosh1743]

Very helpful video thanks :-)

[@madhvafakare818]

Thanks Mr. Andersen I understand more faster by your video rather then learning book
What kind of software you are using to editing such video.

[@BooMi603]

Thanks a lot brother....

[@anandboyzable]

hey can you upload a video regarding how to break the components of the forces in FBD...

[@sneakymarteen]

A climber rappels*.
Great video, thanks!

[@dannyengels5690]

thanks a lot man! I wish you were my teacher!!

[@brianho6625]

How about the "Normal Force to the floor" for the BOX/Body,
which seems not mentioned at video (9:00 minutes of this video)?
The rest of the video is well explaining!

[@Technecon]

He did show it at the end of the example though.

[@bjar]

thanks

[@Spider2015]

Please, if you could do a video for each chapter in a physics textbook, you would be the savior for soooo many physics students. (and Im suppose to be the "super genius" and Im saying this)

[@ScienceguyOrg]

Great job on the videos, with the golf ball that is hit, what is the kinetic energy, is that not a force?

[@davidlipps1265]

Kinetic energy is not a force but is the measure of energy contained within a moving mass. (1/2)(mass in kg)(velocity in m/s)^2 = Joules of KE Kinetic energy can be transformed into a force when a mass contacts another mass. Forces change accelerations, accelerations change velocities, velocities change positions. Since KE of mass 1 doesn't change the acceleration of mass 1 it isn't a force acting on mass 1. However, the KE of mass 1 can be transformed into a contact force that acts on mass 2 which will change the acceleration of mass 2.
Hope this helps.

[@ScienceguyOrg]

Thanks David, I know you are right, I just having a little trouble getting my mind wrapped around this. I think about my hybrid car, power it to a certain speed and then take my foot off the accelerator and it is coasting. Newton says it will keep moving unless acted on by another force. There is friction pushing back and it also turns the generator. It just seems to me that forces work in opposing pairs.

[@davidlipps1265]

My pleasure. Talking about these concepts solidifies my own understand. Unfortunately, Newtons laws aren't always as intuitive as we'd like them to be. Sometimes I have to really work at finding ways to make sense of things that I know are true but are hard to translate into everyday life.

[@mathgang1]

Resistance force = a force such as wind resistance or friction

[@joedodod138]

2:47 and pause tell me if u get it

[@yoinkusBloinkus]

wait NeO EXISTS?!?! (matrix film)

[@anandboyzable]

liked the video (the spring sound could have been avoided)..

[@jangtheconqueror]

OMG portal!!

there's a pro-wrestle with your name....

[@steross1981]

Haha Fapp

[@joedodod138]

yesssssss

[@higuys8154]

:D:D:D:DDDD

[@audax956]

Rappels not Repels... Anyway...
This is a homework video for our class...
It helps!

[@benchabot6886]

saaaame

This comment section is really, _really_ immature.
Also yo Mrs. Carney's class.
