Interestingly the resistive force and the restoring force are 90 degrees out of phase also for damping. Since the air resistance force is proportional to the negative of the speed (or speed squared).
I was taught that what you called heavy damping is actually overdamping. Heavy dampening is just like light dampening but the amplitude decreases faster, that’s what I learnt at a level
So all that theory, Sir, How do we derive the time 't', (light damping case) or when that bob pendulum swing has stopped oscillating for practical reasons?
At 3:57- how come it increases the amplitude because if it is 90 degrees out of phase shouldn't destructive interference happen, so wouldn't the amplitude decrease?
Hi , was really useful and just wanted to ask about the destructive nature of resonance for A levels and i hope this does not get lost in the comments. Also its the 100th comment :)
Just to clarify, if the natural frequency of a system was 5Hz, would a driving force of frequency 1Hz or 10Hz (or both) cause the system to resonate? Thanks again for all your videos!
+Tim Forrer Great question. Driving frequency being a fraction of the natural frequency is not something we talk about at A-level, so we say 1Hz would not result in resonance. 10Hz, yes.
i have a question so does the external frequency match the natural frequency? for example a wine glass has a natural frequency at 40(example) an external force such as a singer must reach the frequency or higher in order for resonance to occur and for the glass to break?
@@ScienceShorts I know just found it funny, also your videos are actually so helpful my teachers are terrible and I've learnt most of what I know from RUclips so thank you
Good but you didn't say why if driving force frequency = multiple of natural frequency ,it will has the same effect ... What I think ,, if this happened ,,, the bridge will break ...??
+Lil'Jinae Nafamard Nope, no formula with it. The only question you could be given is for example "the amplitude decreases by 5% every second - what will it be after 10 seconds?", so just amplitude x 0.95^10.
an application for HEAVY damping are door dampers, they are used to prevent doors from completely slamming shut. and an application for CRITICAL damping is a car suspension system to prevent the car from oscillating after hitting a bump in the road
Hi, could u do communication system. Like FM and AM, bandwidths, etc.. Also, please do electronics. Like amplifier and etc. If possible, please make a vid on medical imaging as well. These are the only chapters that are missing for CIE A level Physics syllabus this year
Re-uploaded due to a mistake. Thanks to Henry Bamber for spotting!

I really appreciate teachers who explain to their students as if they were babies.Thank you. This is really helpful

Becoming my physics teacher
I have an exam at 9 AM and rn it is 8 AM. I am just so thankful to you for making this so easy for me.
how did the exam go?

You explained this better than my 3-hour physics lecture. Excellent!
simple yet informative....perfect!
Your videos are way better than the stuff my teacher did in class. Thank you so much!!
You've saved me. I finally understand damping 😂
Wish more people could see this guy's videos and appreciate him like I do.
Thank you! Really helpful for my part 1 anaesthetic examination!
Excited for the exam tomorrow
Thank you for explaining this.
I learned alot. You are really good at explaining things.
Interestingly the resistive force and the restoring force are 90 degrees out of phase also for damping. Since the air resistance force is proportional to the negative of the speed (or speed squared).
Perfect elucidation.

same here
Hehe
AQA?
same
It's Damping
Thank you so much! You're a great teacher :D
That was really well explained thank you!
Thank you for your service!
What’s the difference between heavy damping and overdamping?
So all that theory, Sir, How do we derive the time 't', (light damping case) or when that bob pendulum swing has stopped oscillating for practical reasons?
4:06 what sorcery!
Really good explanation
Ty mr
such an amazing example!
how do you find the perfect resonant frequency to get back the highest amplitude?
well explained it made look this topic so easy thanks 😀
Thanku so much for your effort sir , I got question # Resonance is sharper for heavy damping or light damping? Please answer.
Great vids, thanks. If you increase the mass of a resonating object will resonant freq increase too? Thanks
Thanks. It was very helpful
Thank you very much.
Thanks for the helpful video!!
Great stuff!
notes are noted 👍👍👍
1:06 - 2:47
Thank you so much
At 3:57- how come it increases the amplitude because if it is 90 degrees out of phase shouldn't destructive interference happen, so wouldn't the amplitude decrease?
that was really useful *thumbs up*
You just may have literally explained the the logistics & science of how megalithic structures were built!!!!
Thank you soo much this is very helpful
Thnx man super super useful
Thanks . Good job. Internet and your video can keep my dream becoming real

@@ScienceShorts 10 Hz should not.
Why does it need to be 90 degrees out of phase with the restoring force? Thanks for the videos!!!
it cancels out the restoring force from bringing it back to equilibrium thus increases the amplitude
Cos90=0
Very Helpful Thanks a Lot
Damping is in phase with restoring force?
thanx, great work
Thank you very much ❤️❤️❤️❤️
Really helpful 🤝
i didn't get the 90 degrees bit, why would the amplitude increase if its out of phase?
thank u man u saving my life
i have a question so does the external frequency match the natural frequency? for example a wine glass has a natural frequency at 40(example) an external force such as a singer must reach the frequency or higher in order for resonance to occur and for the glass to break?
thnx for the help
What does the driving force being 90deg out of phase with the restoring force mean?
This helped me to understand Economics term😂
Please provide a mathenatical approach with a limit format, say when Applied Freq -> Narural Freq, Amplitude -> Infinity.
No.
is this resonce is the cause for breaking glass when singing....if so...what happens there???
thank u sir
great video
what about overdamping force ?
What is natural frequency?
What about over damping and under damping? Which one is the same as light and which one is the same as heavy?
Over damping is the same as heavy and under damping is the same as light.
When he says sin wave but means cos lol
Same function just shifted lol
@@ScienceShorts I know just found it funny, also your videos are actually so helpful my teachers are terrible and I've learnt most of what I know from RUclips so thank you
What about forced vibrations?
.
you didnt upload about critical damping, light damping and heavy damping, did u ?
Thank you for this video!
Good but you didn't say why if driving force frequency = multiple
of natural frequency ,it will has the same effect ... What I think ,, if this happened ,,, the bridge will break ...??
Gr8 vid
I'm regards to the graph of damping how would you show or explain that it is decreasing exponentially? Is there a formula
+Lil'Jinae Nafamard Nope, no formula with it. The only question you could be given is for example "the amplitude decreases by 5% every second - what will it be after 10 seconds?", so just amplitude x 0.95^10.
What are some applications of heavy damping?
an application for HEAVY damping are door dampers, they are used to prevent doors from completely slamming shut. and an application for CRITICAL damping is a car suspension system to prevent the car from oscillating after hitting a bump in the road
Thank you so much! But 1 question will the frequency be affected due to change in amplitude ?
no, the frequency always remains constant
Thanks
Why does it not go on the negative x axis during heavy damping
Because it does not complete an oscillation
