Brilliant! I retired from teaching in 2018 at a high school in Cape Town. I was born in 1955. My dad was a physics teacher. I also taught physics for a while, but your teaching is a stunning revelation to me! Thank you very much, Prof Mason.
Start every projectile motion problem with the Displacement Equation (DE) and the Velocity Equation (VE) for both horizontal and vertical directions. Next modify the equations to reflect your known values - creating a toolbox! Then solve for your unknown quantity. Good luck!
Thank you so much. $ for college tuition is worthless when you have a teacher that doesn't explain things well. This was my second time taking physics and I have an exam tomorrow and did not understand projectile motion. The way you explained the process was clear and concise, and the effort and production that you put into making your videos neat, informative, and short at the same time is awesome. Really cannot thank you enough!
Reviewing for a physics certification test...THANK YOU!!! You helped make sense out of all the formulas in the toolbox! Instead of trying to memorize these formulas, you helped me understand where they come from! Yay logic!!!
Amazing explanation that helped me understand my college physics lecture. Thank you for sharing! I wish my college professor were as good as explaining the 2D motion problems as you explained them. Thanks for your help! Hoping to pass Physics this college semester and your video helps clarify some concepts that I had been struggling with.
Nicely done. One important quibble though: g is a "constant" and is never negative (just like "e" is always 1.6 x 10^-19 C though the charge on an electron is -e). What you should have instead is ay = -g when your +y direction is upward.
I'm thinking of starting my own youtube channel dealing with tutoring physics. I think you did a great job but I think someone learning this material would benefit from seeing the material being filled in in a linear fashion, top to bottom.
thank you a lot it took you a few minutes to explain this and for me to understand...while in class it took me 3 weeks to just get confused if you get what i mean.
man ty so much, ur a great human being and u helped me alot with the exam i'm having in 3 hrs i'm so grateful and i wish u nothing but the best in ur life and i'm gonna be back to ur channel whenever i need something :) thanks again :)
Thank you for the very organized, neat handwriting. It helps clear everything up when i'm in a class with so many people and can't get the individual attention I need for some things. As mentioned below, please ditch the yellow sharpie, on paper it might be distinguishable but over a youtube video it's hard to see. Thanks again!
@@jlbenson I used to have an annotation that pops up with this correction. I have no idea where it went. Thanks for letting me know, John - will look into this!
Wow! You're really talented. You find the way to make things easy and funny with the right concepts. Thank you so much. You should continue making more videos like this, your "how to solve..." are fantastic!
I had trouble with the quadratic because my TI84 Plus Silver requires parenthesis before the square. So (30sin(20))^2. so... (30*sin(20) - sqrt(30sin(20))^2 - 4(.5)(-9.8)(100)) / (2(.5)(-9.8)) Hope that helps somebody else.
@Jesse Mason would you be able to explain how you used the quadratic equation to get time, I have tried it on my own and haven't gotten the same answer, very much appreciated, this is a great video !!!!
In projectile motion, horizontal velocity is constant, so it's total velocity at its highest point it equal to the horizontal velocity. However, it's vertical velocity "AT" its highest point is zero.
+Sourav Ghosh Pretty much the same thing. List all the horizontal and vertical competent information listed downward, SUVAT. Some information is already known, horizontal acceleration is zero whilst vertical is -g (given that 'up' is taken as positive). Also, at the maximum height final velocity is zero (or initial if considering the right hand side). Then select the correct equation with the variables you know and one unknown. Give me a example question if you want.
Thank you! I'm not entirely sure I get these but I think its better than what I had started out with. I don't fully understand the imi hat and j hat things but i guess it's fine.
Jesse Mason I wish that your channel's attributes match with their membership criteria. All the best, sir and keep making those great physics videos!! :)
I'm not that great with these problems but (correct me if I'm wrong) I think your displacement in the y direction should have been equal to the height of the cliff, which in turn would have given a different value for t...which affects the rest of the problem. I could be wrong. Just saying.
So are those equations what I use for all/most projectile motion problems? Ps- thank you this video was very helpful! My college professor doesn't like to teach so I have to do it through UA-cam
How do you find the distance of a horizontally shot projectile if the only given is the vertical displacement and the velocity? There is also a man standing 1500 away from it. Please help me!
You know what I’ve learned from this and the comments 1. All of our actual physics teachers are trash at teaching -I can def relate mine sucks 2. We are watching this before a test/exam -u bet I am 3. Projectile motion.
Hi Jesse, Very well explained the concept of projectile. Would you be able to add more problems from Engineering Dynamics on various diff. topics? Appreciated and thanks for clarifying projectile approach.
But if you are shooting something off above the x axis, then Yo is the height at the beginning, not at the end of impact when the projectile hits the x axis when Y=0, so wouldn't you add that original height into the quadratjc and then you're solving for the time at the beginning, not at the end.
i tried to do this on my own but when calculating the time, the numbewr inside the radical was negative, (104.4-2000) ?? what have i done wrongg? please someone help me out with this

13 min video taught me more than a three hour lecture...
Glad that you found the toolbox method useful, Dean! Feel free to share this video with your teacher. =)

Remember that time I fell in love with a video and the clarity it brought?
+Chelsea George I do, I do! Cheers from Detroit, Chelsea!
@Anthony Willson: If you can tolerate me sounding drunk, click the Gear button below the video and set me to 0.5 speed.
i did this. and it totally made my day! Thanks.
Awesome reply :D
Jerry Li yo, are you studying for the PQ as well? Good luck!
Jerry Li Thanks. =)
It reminds me of my typing teacher in grade 10. Mr. Dudley was a great guy but he smelled funny and I didn't suffer from anosmia.
Nice vids, thanks!
I wish I could give you the money I give my useless professor.
+FrostByte how does he get 5.68s? what is y0?
Sholla Hanafiah y0 is displacement bro taken in projection cocepy
is it 100m?
That makes two of us.
Yup. I was right along with him, then he skipped solving the quadratic, and I'm out.
Start every projectile motion problem with the Displacement Equation (DE) and the Velocity Equation (VE) for both horizontal and vertical directions. Next modify the equations to reflect your known values - creating a toolbox! Then solve for your unknown quantity. Good luck!
You made physics understandable for the first time in my 5 years of university life! God bless you Jesse!
I just watching this now and in 15 minutes I have a test on this. I LOVE LIFE!!

Thanks, SHEMA! =)
Idk what's more beautiful...the steps or your handwriting
awesome man ...who the hell are you .....love to study from you
I am Batman, no wait, I am Jesse Mason.
I learned more in this video than in 3 weeks of instruction. (at least about these types of problems)
The clarity... Wow you're an amazing instructor
Thanks, Daniel!
This saved my academic life! Thank you!
The magnitude of g is negative, Ian!
its an honor to see you, professor stoddard and my favorite guy Ryan ... i miss physics with you guys
Hi! Which class were you in, Prasoon?
ONE OF THE BEST LECTURE I HAVE EVER SEEN PROUD OF U MATE
+abdullah shafiq how did he get 5.68s? what is y0?

You should explain further on since most people often dont know what Vy, Vx and etc. are but thanks for your knowledge and sharing it
so late on the boat but you just saved my entire friends and me from failing , thank you so much
Glad to lend a helping hand, Lawliet. =)
you lost me after the first 1min and my physics half yearly is tomoz rip me
Hahaha how did you do?
Miss Spectator 13%
feelsbadman rip IB physics exams coming up in about a week :/
@Donald Trump yeah no wonder orange.

I helped you. You saved yourself. Nice work, Nani!
Used your video as part of a review for my Dynamics exam.
Outstanding!
my teacher is teaching us the "chart method" but combined with this its 1000000x more understandable
+Silverfrost128 Never heard of the chart method.

Hello sir. I cannot thank you enough for explaining this all to me...I am currently in AP Physics C (as my FIRST physics class), and this makes sense.
Great to hear it helped, Adam. Come back for Kirchhoff's if you take physics 2!
Wow! You're really talented. You find the way to make things easy and funny with the right concepts. Thank you so much. You should continue making more videos like this, your "how to solve..." are fantastic!
you are so good and precise, I should've watched this before going to the lecture, wow nice. I will remember the singing in my test, haha!
Your teaching technique is wonderful and awesome...I like the way u teach
Glad to assist, Celine!
you're the best of best physics teacher
I had trouble with the quadratic because my TI84 Plus Silver requires parenthesis before the square. So (30sin(20))^2.
so...
(30*sin(20) - sqrt(30sin(20))^2 - 4(.5)(-9.8)(100)) / (2(.5)(-9.8))
Hope that helps somebody else.
Thanks for your help I was using positive for gravity which gave me math error
Looks like you helped in other ways too
@@dontbeserious5153 same!
Great video. Really well made, interesting, to the point, and informative. Thanks bud.

That was legit the most helpful video I've ever seen!
Thanks Man. That was very swift and smooth without much hassle..
Hassle-free fizix!
you made numerical problem a game to play full of concepts amazing diagrams and that bullet fire sound from cannon )))))
This is amazing! I'm having a hard time understanding Physics problems like this and this really helped me a lot! thank you!
This was explained wonderfully. Thanks much and hopefully I can do the method by myself
Please make a physics series . The way you call the velocity and the sub ohs is different but still makes life easy
I feel like I’m about to have a nervous breakdown god why did I have to take physics
For finding the range, when y=0, you are better off using the null factor law which is a breeze compared to using the quadratic formula. :)
this deserves a sub. Thanks man, really helpful!
Great video! OMG, you're so much more awesome than my physics prof!
Glad you liked it, Maryann!
fantastic demonstration and editing
I might just pass my test tomorrow because of this, wow!
How'd it go, Cass?
Got an 80! It was mostly conceptual problems so I think I did alright on the math parts. Waiting on our FRQ scores though.
@Jesse Mason would you be able to explain how you used the quadratic equation to get time, I have tried it on my own and haven't gotten the same answer, very much appreciated, this is a great video !!!!
In projectile motion, horizontal velocity is constant, so it's total velocity at its highest point it equal to the horizontal velocity. However, it's vertical velocity "AT" its highest point is zero.
ur an absolute lifesaver
sir you are genious but sir what to do when the projectile is not on a given height
+sourav ghosh
You can just set the initial height to zero, and proceed from there.
+Sourav Ghosh Pretty much the same thing. List all the horizontal and vertical competent information listed downward, SUVAT. Some information is already known, horizontal acceleration is zero whilst vertical is -g (given that 'up' is taken as positive). Also, at the maximum height final velocity is zero (or initial if considering the right hand side). Then select the correct equation with the variables you know and one unknown.

You're welcome from the top of my head, Saugat! ;)
I love the way you teach.
Thanks, Kevin - that means a lot to me. =)
i do not need to watch it over again as i ask my professor to teach me again and again same problem hahahhaa
Amazing lecture! Subscribed and saved to my playlist! Thank you!
Thank you for making this video. I learned from it.
i enjoy these lessons cause I understand totally
+Sonia Mwamba Thanks, Sonia! Cheers from Detroit!
Amazing!! Thanks a bunch for the clarification
+Kareem Sasa Glad to clear it up for you, Kareem!
you're video is awesome and perfect and soooo helpful.. we need more..
Your channel deserves more attention than it gets atm. I suggest you join makers studio or something. It may help...:)
Makers Studio? I'll look into it. Thanks, Mohammed!
Jesse Mason
I wish that your channel's attributes match with their membership criteria.
All the best, sir and keep making those great physics videos!! :)
Mohammed Zaid Cheers, Mohammed!
I'm not that great with these problems but (correct me if I'm wrong) I think your displacement in the y direction should have been equal to the height of the cliff, which in turn would have given a different value for t...which affects the rest of the problem. I could be wrong. Just saying.
Yeah I was thinking the same thing...
to get time, he did input the hight of the cliff as the initial y position.
the decplacement however, equals zero at the time of impact.
So are those equations what I use for all/most projectile motion problems?
Ps- thank you this video was very helpful! My college professor doesn't like to teach so I have to do it through UA-cam
This simplifies every aspect of the problem! Thanks Jesse
awesome method of teaching. it really helpful
The quadratic formula song is now stuck in my head... well at least I wont forget it in the next test :)
I heard it once and it stuck. Math ear worm!
you saved my life sir !! Thanks a lot
Glad to help, Alex!
Great video, Thanks for putting so much time and effort into it
Nice to have my efforts noticed. I spent the better part of 2 weeks on this one.
You make physics fun!!!!!!
How do you find the distance of a horizontally shot projectile if the only given is the vertical displacement and the velocity? There is also a man standing 1500 away from it. Please help me!
Wish you could teach this to our "(Ph.D)" Professors at College..
This is such an amazing explanation!!!!!
Glad you like it, Rabbiyah!
Just in time before AP Physics Projectiles Exam
You know what I’ve learned from this and the comments
1. All of our actual physics teachers are trash at teaching
-I can def relate mine sucks
2. We are watching this before a test/exam
-u bet I am
3. Projectile motion.
You should do more videos like this! Great stuff! :) Cheers!
So how would I calculate the angle of impact on a parabolic trajectory? If I were given a ballistics chart based on known drag coefficient spec?
really helpful sir, keep uploading more such videos thank you.
mudaliar kushal Will do - thanks for the encouragement, Mudaliar!
You re simply awesome.....post some new projectile topics.....
What sort of projectile topics would be helpful to you, Aditya?
The explosion sound effect made me flinch lmao
I absolutely loved this video!
Thank you so much and greeting from Australia
Hey I was just wondering...we have used the formula for range and I get a different result....
I have a question, sir. Why is the DE not = Vot + (1/2)at^2? What is the Xo/Yo in the end, represent?
Hi Jesse, Very well explained the concept of projectile. Would you be able to add more problems from Engineering Dynamics on various diff. topics? Appreciated and thanks for clarifying projectile approach.
Had to learn this in a day yo
I kindly request you to make videos on electric field and charges, and solving problems related to magnetism and matter
Noted, Nikita!
Im confused on the time equation/ what do you substitute for the Yo in the quadratic formula?
But if you are shooting something off above the x axis, then Yo is the height at the beginning, not at the end of impact when the projectile hits the x axis when Y=0, so wouldn't you add that original height into the quadratjc and then you're solving for the time at the beginning, not at the end.
This is crazy good and useful
Great explanation. Thank you!
+denmcca Cheers, denmcca!
God must clearly be real because this video is a miracle of life
is it only me, or the cannon really look kind'a weird.......you know that thing.....anyway you're sure better than my physics teacher....
i tried to do this on my own but when calculating the time, the numbewr inside the radical was negative, (104.4-2000) ?? what have i done wrongg? please someone help me out with this
The toolbox was sooo helpful!!! Do you do any harder sruff? Like when we have two football players that are running n throwing a ball back n forth?
Hi Franchesca! I've never attempted a foosball problem like that. Specifics?
How did you get the -3.59, 5.68 at the range? You shortcut the solution
