Two Dimensional Motion (2 of 4) Worked Example

[@julie9136]

If you're in the comments wondering if you should watch this video out of all the hundreds of other physics videos on youtube - YES. Watch it. This is THE most concise and detailed explanation I've ever seen, this guy is great.

[@stepbystepscience]

Thanks for the great comment, I really appreciate it.

[@israelgershoms6233]

I love you

[@My_Arse]

I second that.

[@eliastioluwani7264]

Thank you sir

[@aaronpicking4935]

Thank you!! I've been struggling with these concepts for days because of not being able to find a "teacher" that's efficient while going step by step.

[@stepbystepscience]

+Aaron Picking Thanks for the great comment, as you noticed I try to get right to the point and just go step-by-step. In fact you can find a listing of all my videos at my website, www.stepbystepscience.com Thanks for commenting!

[@bma6469]

You deserve any kind of comments you wish sir because you're making a tremendous impact with your generous contributions.

[@stepbystepscience]

Thanks so much for the nice comment!

[@walttothjr7370]

Thank you for taking the time to explain this particular concept. In my opinion your approach was, clear, to the point, and focused on the elements of importance. This focus makes the lesson easier to follow. Thanks again. Sincerely Walt

[@stepbystepscience]

Thanks for taking the time to write such a nice comment. I try to get right to it and explain everything in a simple step-by-step manner. Thank you for noticing.

[@ccandcoffee]

I am struggling and in fear of failing physics right now. Your videos are very easy to understand. No unnecessary comments that confuse me more, step by step explanations. Thank you so much. I'm going to binge watch your videos!

[@stepbystepscience]

Glad to hear that my videos are helpful. Best wishes to you.

[@jenniferibarra4535]

I am a sophomore at New Mexico State University and I am preparing myself for my first midterm. I just want to thank you for uploading this video is really helping me understand motion in 2D.

[@stepbystepscience]

I hope the mid term goes well and thanks for the comment.

[@Peakimpatience]

I was feeling hopeless and lost before I found this video. A lot of professors rely on previously acquired mathematical knowledge on the student's part. They believe they can demonstrate the broad strokes and that the student should be able to intuit the rest. I can't tell you how much I appreciate videos like this. You live up to your screen name. Thank you for breaking everything down.

[@stepbystepscience]

I try to go over everything step by step from beginning to end. Great that you found the videos helpful.

[@kelliekirch4780]

This video made so much more sense than other videos of this sort. I really appreciate you breaking it down for me.

[@stepbystepscience]

No problem, glad that you found the video helpful.

[@nasitaislamnooha7343]

You have changed my mind setup about physics. You just narrate it like a story. Great work, Sir. Thanks. To every one the definition of teacher should be the example of you.

[@stepbystepscience]

Wow, thank for that great comment.

[@user-jp8no7ng7k]

6 years later, still the best video explaining this topic out there. seriously saving my test tomorrow

[@stepbystepscience]

Thanks for the vote of confidence. Best of luck!

[@footballhighlights8005]

Thank you. U better my classroom teacher. You left me with no question

[@oslaidyscabrera9718]

The best explanation I ever heard, you adapt perfectly to this time generation combining visual and hands-on learning styles. Thank you so much for all your work, it helps me a lot.

This has been much appreciated and will be back to watch more videos that I have trouble in. I believe physics is taught inefficiently when using just still power points. This video has clear explanations (provided student has some type of background knowledge on the subject) and animations that simplify concepts. Well done!

[@momemimo_]

my professor never did a negative on the gravity's value; and she kinda taught us that in the kinematic equations it's positive if it goes down and negative if it goes up

[@stepbystepscience]

This can be a bit hard to explain here......but I think it would be fair to say that the acceleration due to gravity (g) always points in the negative direction (down). Two dimensional motion like this is basically free fall. When the object is moving up it is slowing down and when it is moving down it is speeding up. Try to get used to being consistent with your signs for velocity, displacement and acceleration and you should not run into any problems. Otherwise you may have to fudge this a bit sometimes. Does that help?

[@davidbain701]

It's like the velocity in the X direction is the platform that you keep compressing against gravity like a sping , till you can't compress it any more .So the downward motion is the equal and opposite reaction so you still need the same platform to relay this force on the way down .
