Energy, Work & Power (22 of 31) Work from the Force vs. Displacement Graph, No. 1

[@SirBinski]

Have an IB Physics test tomorrow and you greatly helped to refresh my memory on work. Thank you for your effort, it is not going to waste.

[@superpooper5414]

howd you do on that test

[@stepbystepscience]

Good luck on the IB test tomorrow +LucasLandryHyatt, I am glad the videos were helpful and thanks for commenting.

[@AK-jy2fb]

I am so glad I came across your video! I have been in tears over this physics class and you taught me something in under 6 minutes that I couldn't even understand in 3 hours of class. I only wish I found them sooner. Hopefully if I pass this class I can watch these for physics 2. Thank you!!

[@JennyShin-me6dn]

Thank you so much for your video and lecture!!!! SO EASY TO UNDERSTAND

[@stepbystepscience]

Happy to hear that. Thanks for watching.

[@julesvido]

Can I just say thank you here, you have taught me in 5 minutes what it took my IB physics teacher 12 hours to not-teach me. so thank you, you have probably saved my ass for tomorrows exam

[@stepbystepscience]

Thank you for commenting Giulia Vidoni , I hope the exam goes well tomorrow

[@TechnoGenuine]

Can you please explain me this. When do I use Area formula and Work Formula>?

[@nicolevolek8018]

I have a fear of graphs!!!!! this is helping

[@vtk2944]

Nicely explained. Simply superb. Thank you👏

[@stepbystepscience]

So nice of you, thanks for your comment.

[@Thesaviorsway]

So w is equal to integral of force x distance. That's why the Area under the force x distance graph shows work done. I had a lab on this and found the answer.

[@stepbystepscience]

yes.

[@mbalentlemichelle2780]

Thank you so much I understand it now .May god bless you❤🎉

[@stepbystepscience]

You're very welcome and best wishes to you 😊

[@gabrielcavuquila4380]

Thank you very much, it’s so simplified

[@stepbystepscience]

Glad it helped! You're welcome.

[@kimberlyramos8842]

Thank you for teaching.!!

[@stepbystepscience]

You are welcome!

[@uibasma4474]

Hi Sir, I´m having problems understanding why this is the case. Firstly, It seems to me that the graph can be used only when a force is applied continuously throughout the displacement. It would not be accurate if the object is propelled by short bursts of force. Secondly, If the force applied is not linear as you have depicted here, but rather parabolic, then would the work still be equal to the area? In other words, since in W = F*d*c, d is the displacement caused by F, then wouldn't irregular force cause irregular displacement? How do you then prove the sum of these Fk*dk equal the area?

[@stepbystepscience]

Yes, only if the force is constant. If the graph is curved then you would have to use calculus to determine the area under the curve.

Thank you

[@agoodchoice8942]

It helps me thank you sir🥰

[@stepbystepscience]

Glad to hear that, you're very welcome.

[@nehamartand7499]

Thank you! Good for NEET exam!

[@stepbystepscience]

Great

[@ibrahimzuraik727]

thank you , this is helpful

[@dineshpatil839]

how to find work under hyperbolic curve

[@stepbystepscience]

Calculus

[@vrindasharma1258]

It is really helpful

[@stepbystepscience]

You are very welcome, thanks for commenting.

[@ajaymourya3527]

How can we find kinetic energy if object start with initial velocity u

[@RezzysChannel]

K = 1/2*mv^2

[@kimberlyramos8842]

I do understand when my prof teaching. But, when it's my turns to answer the problem. I do not know if it's correct. It's like I have no bases.

[@stepbystepscience]

You can do it, and it's always ok to ask questions!

[@babunethala1]

Very Good and helpful!!

[@stepbystepscience]

Glad it was helpful!

[@anis-fs9wh]

thanks..

[@stepbystepscience]

You are very welcome!

[@urdusongsmaster3970]

Thanks sir

[@stepbystepscience]

Welcome and all the best

[@abdulazizhussain9897]

thanks

[@stepbystepscience]

You are very welcome.

[@animefangirl098]

Why is it 3 m instead of 4?

[@pearspeedruns]

gir0999 11-8 is 3. 8,9,10,11 has four numbers, but the difference is still three

[@nibiru3902]

thanks dude

[@stepbystepscience]

No problem man!

[@shacopoptantix4617]

Nice

[@stepbystepscience]

Thanks

[@kimberlyramos8842]

I really having a hard time in my physics subject.

[@stepbystepscience]

I hope the videos are helpful.

[@eadenjensen2259]

Im writing my Physics IA and a friend sent me this cause I confused myself on this. 🙃😖

[@stepbystepscience]

Did the video help?

[@JuliaShikokola]

Thank you
