Toy Car UAM Problem with Two Different Accelerations

[@Andrew_Hanford]

Why these videos aren't more popular is a mystery. Very well done. Seriously.

[@FlippingPhysics]

Rather than talk about the physics of the new video (slightly more complicated UAM problem with two interconnected parts), I want to talk about my acting. Oh yeah, my acting. I have been working on, with my wife's help, what my characters do when they are not talking and how they interact. Notice how @ 13:30 Billy and Bobby basically have a quiet race to see who can use their calculator faster and Bo is just disgusted by it. Although I think my favorite moment in the video happens @ 12:10 when Bo notices a pencil on his desk. Yep, who knew I was going to be an actor? Or maybe not.

u r Awesome at every thing. .. 😍 this actually make us to love you . Even that much distance doesn't matter 😂😂 love from Pakistan

[@aji5016]

The details are everything

[@atarah7294]

I think Bo is really smart because he don't use a note book to write problems and don't use a calculator .

This is very helpful and entertaining!

youre the best teacher here in yt

[@glr1246]

Thank you so much ! I understand at the same time at the students lol. By the way you make me fancy having class with myselves 😂

[@FlippingPhysics]

You are so welcome!

Is memorizing equations an inefficient way? Using an equation is important, but I don't know how it's derived.

[@FlippingPhysics]

The issue with showing how the Uniformly Accelerated Motion equations are derived is that it requires calculus. I show derivations of two of the UAM equations in this video, if you are interested: kzbin.info/www/bejne/eGfFmmh-ZtWqo6cm27s

such a helpful video

Thank you ❤️

You are doing a great job 🙌🔥

Thank you!

for displacement 2, why did I get a different answer when using the equation1/2 (vf+vi) delta t1/2 (.22+2.496)1.1I got 1.4938. Even though the total displacement ended up being 3.4906, 2 sigfigs the same answer, 3.5 m why is my answer different?

[@alphawtel3157]

You didn't us 0.219

[@shaikhnbake]

@12:41 When solving the displacement for Part 2, why does using the same UAM equation for part one not work (I tried it and the answer I got was 2.5773) even though all the variables needed are available(V2f, V2i, and delta t) Any help would be very much appreciated Thanks :)

[@FlippingPhysics]

It does work. V2f = 0.219 m/s, V2i = 2.496 m/s, Δt2 = 1.1 s, results in Δx2 = 1.49325 m/s, which is the same. I am not sure where your error is.

[@shaikhnbake]

UAM equation I used for part 2 delta x2 = (1/2)(v2f+v2i)(delta t2) Answer I got (1/2)(2.19+2.496)(1.1) = 2.5773 m/s

[@shaikhnbake]

The UAM equation you used for Part 2 worked with me when I used it, but when I tried using the UAM equation from Part 1 to find the displacement for Part 2, I ended up with the wrong answer. Thanks for replying in the first place, your a living legend.

[@FlippingPhysics]

V2f = 0.219 m/s ≠ 2.19 m/sPlease take a moment to think about how much time you have spent working on this and all it really comes down to is being careful with reading and writing. So often students rush through problems and think they do not understand the physics, when all they really did was make a simple mistake. Slow down. Be careful. Read carefully. You will understand more and you will learn faster. Best of luck and I hope that helps! (Also, I'm not trying to be snarky; just trying to give some legitimate advice) (Double also. I just looked up "snarky" and this is what the dictionary said: "cranky; irritable: Bobby's always a bit snarky before his nap." I agree. Bobby is always a bit snarky before his nap. 😀)

[@shaikhnbake]

Wooooow. Thanks once again, couldn't believe I made such a simple mistake.

Is the Motion of planets around the sun, an example of uniform velocity motion?

[@FlippingPhysics]

I don't know what "uniform velocity motion" is, however, the motion of planets around the sun is not an example of uniformly accelerated motion.

[@jacob5292-s7l]

I used the rounded .22... not .219

[@aji5016]

13:04 ??? Bo is secretly an innate genius...

[@juanguio5932]

lol, i saw that too

[@juanguio5932]

If you think about it, it gives his character a deeper meaning. It’s not actually that he doesn’t care about learning or the class, he’s just so smart that he’s bored by it. 🤔
