Physics 101 - Chapter 1 - Physics and Measurements

[@SeanR-Singh]

Epic! I will learn physics at all costs.

[@calvin-caleb5816]

For those of you who don't understand how he got s^2. You see acceleration = velocity / time while velocity is equal to displacement / time that's how he got s^2

[@nphy171]

There are few things I don’t agree with. The symbol for kilo is small letter k, not capital. And 4000 is not the same as 4.000x10^3 but just 4x10^3 if you consider significant numbers. Let me know if those are mistakes

[@faithifeoma5566]

Just what I wanted. Thank you ♥️

[@Yani.Devinee]

this helped soo muchhhh i was so lost in class because my prof wasnt explaining well but now i kinda understand more!!!!!

[@hannawaqar1515]

I was struggling eith finding a vid this explains so clearly

[@physicssumo774]

Glad I could be of help! :)

[@snoky0887]

The best tutor ever i love you :(((

[@madonnasilver4516]

Very 👏🏼 informative 👏🏼 10/10

[@Penguinbeast1957i]

Thanks for you good explanation finally I understand significant figures I have a question in 19:09 Can we say 3.25+-0.25 If we can is there is a different between this and 3+-0.5 And which one is better and why?

[@vrutantmehta7173]

At 3:30 it’s supposed to be N= kg*m/s^2

[@physicssumo774]

You're right! I'll try to edit the video to make note of that mistake. Thanks for reaching out!

[@nadinesalnikova1042]

can you explain how do we plug into calculators please? I tried some of the problems like the 117.8097245 into M and I got a complete different answers which maybe I'm plugging it in wrong

[@physicssumo774]

Sure! Maybe I could make a video dedicated to using our calculators in a math/physics class!

thanks for the effort

[@vanessaguevarro6526]

I am a little lost how did u get 0.3048m/7ft if u don't mind me asking

[@physicssumo774]

Thanks for asking! It's 0.3048m / 1ft, and it basically comes from the fact that there is 0.3048 meter in 1 foot. You can find the number on Google. Let me know if that makes sense

[@mohammeds6314]

great, thanks for your effort , keep upload the other chapters :)

[@zuko-s9o]

Thanks a lot! Could you say which books are you using?

[@physicssumo774]

I use Physics for Scientists and Engineers 9th Edition by Serway/Jewett :)

[@amandacrosson3554]

In 20:26, you said the number of sig figs relates to accuracy. Is it accuracy or precision? Great video

[@physicssumo774]

Let's think about this. Precision is relevant when a scientist makes many measurements. If those measurements agree with one another, than we can say that the measurements are precise. However, that does not necessarily mean they are accurate! Accuracy is defined as how close a measurement is to the true value. With that being said, I would tend to say that the number of significant figures tells us about the precision of a measurement, since we do not yet know whether it is close to the true value. If we did know that it was close to the true value, then we would also argue that the measurement is accurate! Let me know if this helps :))
