BS-Electronics System Technology student here. I'm a returning student, having taken a 4-year break from studying due to family reasons. I'm finding it challenging to keep up with my classes, especially in Physics. Although I have some background in the subject from graduating Senior High under the STEM strand, it's still quite difficult for me. I've spent most of my time studying at home, watching TH-cam tutorials, but they didn't really help. I understand some parts, but I'm struggling to fully internalize the concepts and apply them to exercise problems. Fortunately, I found your channel. At first, I was hesitant to watch the full video because I was worried it might be a waste of time if I didn't learn anything. Praise God, I decided to watch your videos completely, and I'm so glad I did. I now feel a sense of satisfaction because I understand everything you've discussed. Thank you, sir, for making the material so simple to understand. I'm confident that I can now keep up with this subject. I hope this video reaches millions of Filipino students so they can also benefit from it. Thank you so much, sir, for this! May you continue to inspire more students like me!
Kuya john rey sison plano ko rin po sanang mag BSME anu-ano po ba ang subject na tinatalakay ninyo sana mapansin mo para makapag advance study ako. Advnce thnk u.
@@johnrheysison9800 thanks po, now alm ko na more on physics pala ang BSME, GOOD LUCK PO SAYO pinagiisipan ko pa po kasi kung ito ba ang kukunin ko na course, More qustions pa po ano kailngan(reqirements, kailngan gawin, etc) kapag mag BSME?
Bakit ako nagkaproblema sa square ng isang negative number? Raising to a power takes precedence over negation so if we just do, for example -2^2 we should get -4. However, if we do (-2)^2 then we get +4, because the negative sign is squared as well. If we want the positive result, make sure we put the negative sign inside the grouping symbol before squaring.
correction lang po, ang Vx at Vy po for 100m NE sa problem #3 ksi 70.71 for both Vx at Vy nya. Not to mention dahil nito dapat ang final answer is 118.52m, 36.80* N of W
May problem po ba na pwedeng gamitin sa lahat ng method? Like pwede po siyang gamitin sa Pythagorean Theorem, Component Method and Graphical Method (parallelogram man or polygon)
possible po ba na ang after solving for the direction, may instances po ba na ang magiging direction is "of north" or "of south" or isusubtract nalang po ulit sa 90?
Good evening po. I just wanted to ask, bakit po inverse tangent paren yung gagamitin para makuha yung direction ng resultant vector sa sample problem no. 2 po kahit na hindi po right angle yung vectors pag ginraph?.
Hindi na po. Since both vectors are lying in the y direction, you can simply add them as how you add scalar quantities. Considering na parehong North, +100 N plus +150N lang.
Kapag nagsummation ka ng x components, iyon ung magdidictate kung East or West. Kapag positive, east. Kapag negative, west. Kapag nagsummation ka ng y components, iyon ung magdidictate kung North or South. Kapag positive, north. Kapag negative, south.
@@scienceclasswithmark-sense2991 sirrrrrr ako din po, di ko getssss.. diba po, positive positive yung x and y edi east at north... bakit po north of east ang sagot? ano po connection nito sa reference angle huhu
By definition kasi reference angle is the angle that the vector makes with the x-axis. Sa madaling salita, laging x-axis ang ating reference. Kaya it is either N of E, N of W, S of E, or S of W.

BSME Student here!! Thank you so much sir mas lalo ko na naunawaan ang physics subject ko
22:19 sir why nakukuha ko sa calculator ko is -44.91?
@@johnrheysison9800 enclose mo lang sa parenthesis ung negative sign saka ung number, bago mo i-square. 👍
Kuya john rey sison plano ko rin po sanang mag BSME anu-ano po ba ang subject na tinatalakay ninyo sana mapansin mo para makapag advance study ako.
Advnce thnk u.
@@leoj.anzanobis1134 mechanical engineering is more on physics kaya isa yun sa need mo mamaster
@@johnrheysison9800 thanks po, now alm ko na more on physics pala ang BSME,
GOOD LUCK PO SAYO
pinagiisipan ko pa po kasi kung ito ba ang kukunin ko na course,
More qustions pa po ano kailngan(reqirements, kailngan gawin, etc) kapag mag BSME?
Maraming salamat po sir, sana laging masarap ulam niya 🙏❤️
You cleared everything salamat lodicakes.

Bro you are good at explaining.
Wondering why you stopped creating such videos.
You should continue. ❤
correction lang po, ang Vx at Vy po for 100m NE sa problem #3 ksi 70.71 for both Vx at Vy nya. Not to mention dahil nito dapat ang final answer is 118.52m, 36.80* N of W
Actually po tama naman po ung 36.5°. Gi convert kasi in degrees after nakuha ung sagot.
maraming salamat po sa pagtuturo niyo, sir
Thank you sir, mas na gets pa kita sa prof ko
Thank u very much po sir. Hoping for more physics videos🙏🙏🙏
thank you so muxh po.🤗
Thank you so much sensei
thank you so muchhhh po
10:53 how
Omg thankssss
Thank you sir
Medyo magulo. Hahaha
hi ano po yung iba ibang reference angles pag hindi given yung angles?
SIN lang po ba talaga pwede gamitin sa y o COS rin pwede?
Greetings sir. I'd like to ask why did u use b/a in the 2nd problem whereas u used a/b in the first problem
May problem po ba na pwedeng gamitin sa lahat ng method? Like pwede po siyang gamitin sa Pythagorean Theorem, Component Method and Graphical Method (parallelogram man or polygon)
Good morning po ano po meaning ng resolution of vector ibang topic po ba yan or simple vector resolution lang yan?
hello po, how about po yung sa Pythagorean Theorem?
Good afternoon sir, paano po makasolve ng speed, velocity, acceleration at displacement sa component method, nalilito po kasi ako
present akoaster Hahahaha
Good Morning Sir
What if South or North po yung direction, ex: 200m South, does the angle become 90° po?
Reference angle*
(2)
sa amin 270° gamit...
pero same lang naman sya sa -90° S
pano 45 sa calcu ko kahit nag shift ako ang lymabas 0.78
possible po ba na ang after solving for the direction, may instances po ba na ang magiging direction is "of north" or "of south" or isusubtract nalang po ulit sa 90?
Sa component method po, ang reference po ay ang x-axis. Kaya lagi dapat "of east" or "of west"
upload upload din ulit ser HAHAHAHA
Good evening po. I just wanted to ask, bakit po inverse tangent paren yung gagamitin para makuha yung direction ng resultant vector sa sample problem no. 2 po kahit na hindi po right angle yung vectors pag ginraph?.
Sir pag po ba same directions Pythagorean theorem padin yung gagamitin for finding the resultant?
Halimbawa po
1st: 100 N, North
2nd: 150 N, North
Hindi na po. Since both vectors are lying in the y direction, you can simply add them as how you add scalar quantities.
Considering na parehong North,
+100 N plus +150N lang.
@@scienceclasswithmark-sense2991 okay sir, Thank you po
Hello sir! student niyo po ako dati sa sfcs hahahahaha
Hahaha ayos ba? Di ko na natuloy. Wala ng time. 😂
why is it 90-40? Hindi po ba dapat 180- theta to get the 2nd quadrant?
90 degrees in every quadrant = 360 degrees
21:15 hi sir bakit po 70.7??? Dpoba 70.71🤔
paano po kapag north or south yung given, ano po yung ilalagay na reference angle and x-component?
e minus mo lang sa 90 ang answer yon na ang reference angle na gagamitin mo
Pano naging 50 degree ung sa 60km , 40 degree
Sir what if 3 po ang given vectors tapos walang direction na given?
Imposible pong walang direction kapatid. Hehe vector nga po e.
can we add 2 vectors po using analytical?
yes po, need nyo lang din po iresolve ung given vectors into its x- and y- components. See sample problem 2 po.
ex: 2 of component of vector is wrong, nagkainterchange po ung formula nyo sa vx ug vy
I believe it is just right. Baka magkaiba po tayo sagot kasi mali po kayo ng ginamit na reference angle.
-94.21² is different from (-94.21)²
Yown. Hahaha maraming salamat po!
Hindi po ba 36.47 w of n yan? kasi pag n of w magiging negative po kasi ang 36.47. TAMA PO BA AKO SIR? HEHEHEHE
N of W po. Reference angle po kasi ung gamit natin.
Can u do english pls..
hindi ko pa rin gets bakit yung direction eh north of east kesa north of west chu chu huhuh
Kapag nagsummation ka ng x components, iyon ung magdidictate kung East or West. Kapag positive, east. Kapag negative, west.
Kapag nagsummation ka ng y components, iyon ung magdidictate kung North or South. Kapag positive, north. Kapag negative, south.
@@scienceclasswithmark-sense2991 sirrrrrr ako din po, di ko getssss.. diba po, positive positive yung x and y edi east at north... bakit po north of east ang sagot? ano po connection nito sa reference angle huhu
ang pede lang pong direction ay n of e, n of w, w of s, and s of e?????
