coincidentally, my homework are the ones he is demonstrating. Luck = 100

[@loganmiller5967]

Damn

[@ninjaaljun7674]

that's sus

[@zamieca.]

To the entire team of *The Physics Classroom* thank you with all of my heart from the Philippines! *Mr. H* I pray for your healthy, bounty full life. 💖🥺 Dont skip the ads ppl.

[@lorenzoerickalyn8748]

Thanks for the video. It help me a lot. Hope to find more!

[@PhysicsclassroomVideos]

You're welcome. There will be more.

[@ABMAN-c4g]

You helping me very much, thank you

[@PhysicsclassroomVideos]

I'm glad it helped

[@Lynxseigh]

WE ARE HAVING AN EXAM ABOUT THIS THING TOMORROW! PLEASE GIVE ME YOUR BRAIN JUST FOR TOMORROW HAHAHAHA KIDDING. THANK YOU SM, IM GATEKEEPING THIS YT CHANNEL. OUR TEACHER JUST TAUGHT US HOW TO SOLVE IT USING THE "SHIFT SOLVE" IN CALCULATOR, LIKE HELLOOO?😓 THANK YOU SM SIR❤

[@PhysicsclassroomVideos]

I hope it went well.

[@user96476]

Thank you, this was very helpful

[@uzairhussain4856]

Hello professor, how can you use the protractor each time without first drawing the coordinate system? Angle measurements without properly drawing coordinate axes would contain slight error

[@pembaonlinemedia]

Thank you, I will practices in the exam room.

[@cliveanawana5289]

Another superb video. I am enjoying this whole lockdown period, mainly because of these your videos. I am improving my Physics knowledge, thanks to you.

[@PhysicsclassroomVideos]

Wow! Thanks for the kind words again!

[@GianYawnYT]

Hi, where did you get the resultant magnitude 2.3km?? 2:32

[@PhysicsclassroomVideos]

I used a centimeter ruler to measure the length of the vector and then I multiplied it by 0.5 km since 0.5 km is equivalent to 1 cm according to the scale.

[@brokensoul_8408]

thank you for this! it really help me a lot 😭😭

[@PhysicsclassroomVideos]

You're welcome. Glad it helped.

[@maximofenn3202]

Straight up fire💪💪💪

[@husseinshahine7185]

Absolutely wonderful video!

[@PhysicsclassroomVideos]

Wow! Thanks for your kind words. Hope you can try some others.

[@macauraohamdi4717]

I guess this guy is my new organic chemistry

[@PhysicsclassroomVideos]

Glad it helped.

[@manickammahendran7891]

Fabulous ..

[@jyalingat]

thank you

[@thesharkest8317]

you helped me out thanks

[@ragadb9826]

Do u mean ruler by scale ?

[@PhysicsclassroomVideos]

A ruler is usually used to create a scale. But a scale is just a statement that equates 1 cm on a sheet of paper to some real world amount ... like 5 miles. For instance 1 cm = 5 mile

[@SureshKumar-yr3sw]

Good 😊😊 👍👍

[@eric-ov5qs]

is there a way to solve for the resultant if there is more than 3 vectors bcuz my teacher gave us 5 vectors to solve for it resultant

[@PhysicsclassroomVideos]

Most the examples in this video are for 3 vectors. But the principle of adding 3 works for 5. Just keep going after the 3rd vector. Add the 4th vector to the 3rd and add the 5th vector to the 4th in the same head-to-tail method.

[@fabiolamoure138]

Aren't you supposed to locate them in their quadrants?

[@PhysicsclassroomVideos]

I'm not sure what you mean by that?

[@mindworker3348]

Insightful

[@PhysicsclassroomVideos]

👍 Thanks.

[@allyzafaithavendano956]

hello how does the 25 degree became 205 degree, I hope your response. It helps me a lot. Btw our teacher share this video to us, and it’s clear explanation, but I don’t get it the 25 degree became 205 degree :((

[@PhysicsclassroomVideos]

25ﾟ South of West means it's 25ﾟ from the 180 direction. That makes it 205ﾟ counter clockwise from East. We have another video on the topic of direction of vectors. That's what you're missing in order to understand this video.

[@allyzafaithavendano956]

The Physics Classroom Thank you so much! I already get the point, the half cartesean plane is 180 degree, and you simply added the 25 degree that you get in the letter c thanks a lot!!! you saved my grade :))

[@siyasingh6076]

AWESOME

[@PhysicsclassroomVideos]

Thank you! Cheers!

[@yeshhhaneesah2583]

I don't understand how u get 40° for vector B. Vector C too. Do you mind explaining that. Thank you:)

[@PhysicsclassroomVideos]

I assume that you are referring to the 4:45 mark in the timeline? If a vector has a direction of 220° CCW, then that would be equivalent to 180° (West) + another 40° rotation past West. It that's confusing then you might need to review our Direction of Vectors video in which we discuss the convention known as the counter-clockwise (CCW) from east convention. That is the convention used for the direction of the vectors in this Example Problem.

How 10.8km

[@PhysicsclassroomVideos]

Scale: 1 cm = 1 km Measured length as 10.8 cm

[@sarahkimani8063]

this was so helpful but damn you need a manicure respectfully

[@PhysicsclassroomVideos]

Yes. You're probably right but at this age I'm probably beyond help. Maybe I'll try gloves next time.

[@zamieca.]

@@PhysicsclassroomVideos no need for gloves! I see the hands of the man helping plenty, those who are determined to learn P6. Those rough hands saved my brain cells from dyiiing. It’s the first time I saw you actually solve in a video. Please do more of it. 💖 I know Sarah meant it well.
