5.3 Springs and Elastic Potential Energy | General Physics

[@MeganClark-Bolanos]

love the channel! but I want to confirm that at 20:39 the answer is 4m/s not 16m/s, since you need to take the square root. thanks again for all the help, I really love the channel

[@killab5952]

Thank U Sir, U are really taking the stress outta learning science, all the way from South Africa

[@ChadsPrep]

Excellent and Welcome to the channel.

[@brendam4159]

fr tho. like why can’t my teacher be like this. thank you teacher

[@munoss-u]

mr superhero you rock! you really made it clear in 27 mins while my prof cant in 15 weeks!! thanks a lot

[@ChadsPrep]

You're welcome - glad the channel helped you!

[@tuckerlanoue9560]

Thank you so much! Super helpful for my exam. I do have one question: Should V1 (written down at 19:29) be squared, as in (V1)^2? And if so, would 16m/s be square rooted, providing a final answer of V1=4m/s?

[@Joshua_mwale]

I also think so.

[@killab5952]

Thank you a lot sir, you are really taking stress outta learning science, Big ups! all the way from South Africa

[@ChadsPrep]

You're welcome - thanks from USA.

[@kileyadams3831]

Should the answer for the first example problem be 4? What happed to the v^2, we didn't square root either side. Thanks for the help Chaddy Daddy, you always help me bounce back!

[@qaisar.sulaiman]

Yeah it should be sqrt

[@ChadsPrep]

Hey Kiley! That first question @16:30 aswer is x = 0.5. Were you talking about a different problem? if so let me know the time stamp

[@nadermunye4879]

20:33 the answer should have been 4 instead of 16? I think you forgot to square velocity@@ChadsPrep

[@nadermunye4879]

also I would personally like to thank you for being a godsend in my physics and organic chemistry classes. You single handedly got me through ochem now you're getting me through physics.

[@ChadsPrep]

@@nadermunye4879 Glad to hear it - Happy Studying!

[@terryrodgers9560]

For problem 2, I used work and got 4m/s, why is that incorrect? Xf = 0, x0 = .1

[@alibilginler]

13:30 always applied force=− restoring force and applied force=kx , right? 🙂😊 thank you teacher chad

[@ChadsPrep]

Correct!

[@NahAtoh]

Thanks for the great work sir

[@ChadsPrep]

You are welcome.

[@nikotmt1739]

very good

[@ChadsPrep]

Thank you

[@sirenofamphitrite4612]

26:16, why is the PE gravity final not a negative force, since gravity is pulling it downward?

[@JenanAlfar]

The gravitational field points downward, but we define the gravitational potential energy relative to a reference height. If you are calculating how much energy is stored at a height ℎ above some reference (say, the ground), then h is positive when the object is above the reference point, and so is the potential energy.

I love u bro. Thx for your help

[@ChadsPrep]

You're welcome!

[@xinyansheng8028]

why does the elastic potential energy equal to the work..?
