best most simple explanation ive ever seen
Kind words. Simple and best dont always go together. Thanks.
Sir prateek jain had recommended us to see the vdo,,,,,he really appreciates ppl like u who r putting their efforts to giv quality educational content to the students ......and he is one of them as well ,,,,nd this one is really amazing nd informative,,,,,,,,,,,,,,,, superb ,,,,,,,,,,,,thanks a lot
One of the best videos on this topic 💖
Thank you so much😭, 1 week worth of understanding became 12 minutes because of this vid🥰. I let you guys know If i passed our quiz tomorrow😇.
Good luck on the quiz. You got this!
@@PhysicsclassroomVideos I PASSED!! thank you so much🥰.
I amazed by the way creating the such complex theory in a simple experiment. I had a very hard time visualising real image. It is awesome. ( Also this video was refferd by our physics teacher sir Prateek Jain )..
okayys , understood !
that is really dope 👀🔥
great video but in my opinion they would be even better if you could derive the equation and test it with few example values to demostrate the reasoning behind it, instead of just telling the formula and asking students to just plugin the values. That way students could come up with the equation themselves instead of just memorizing.
Sir Prateek Jain gang here🤚🏻 . Thank you so much sir for refering this video to us every concept is crystal clear ✨ . Amazing explanation 🤩.
Great tutorial Thank you very much!
Hey boss got a doubt? Do you think this would be helpfulf for Grade 10 international baccalaureate (IB)? BTW great video!
If that's your topic, it will be helpful. It is at the Grade 10 level ( +/- 2)
@@PhysicsclassroomVideos Thanks for the reply also I know that you are busy but I just wanted to ask you a doubt. Well I have like 15 days left before my big exam. Im in 10th grade and I would like to know the 2 things before I share you my syllabus. 1. Does your website cover all of these for 10th grade ib 2. Do you think I should just read the info given on the website regarding the topics rather then watching the youtube video since I have 15 days left Forces & Motion Vectors & Scalars - distance, displacement, speed, velocity and accel distance vs time graphs - speed vs time graphs - Newton's laws of 1 Force and types of forces - equilibrium of forces - free fall - terminal v momentum - impulse - conservation of momentum Forces & Energy Definition of work - types of energies - transformation of e conservation of energy - Gravitational potential energy - Kinetic F Elastic Potential Energy - Power - Efficiency - Sankey Diagrams - Re and non-renewable energy Thermal Energy States of matter - heat and temperature - Brownian motion - M temperature - Types of thermometers - Liquid in glass thermometer - expansion (solids, liquids and gases) - transmission of heat (con convection and radiation) - conductors and radiators - Kinetic theory - internal energy - Gas laws - specific heat capacity - latent heat - boi evaporation Electricity Static Electricity - properties of charges - Coulomb's law - met charging - Earthing - Electric fields Current Electricity - current, voltage, Potential difference and emf de - symbols for electric components - Ohm's law - Resistance also thank you so much for responding to my previous question I knkow that you are so busy!
@gaurava4883 we have about 95% of the topics in our Tutorial section. Be sure to "do something" with your learning. Minds On Physics, Concept Builders, and Calculator Pad are great for that.
Thank you!!!!
You're welcome!
nice!!
Glad you liked it.
Doesn't a filter reflect a significant amount of the color it allows to be transmitted through it? Why does it both reflect and allow for the transmission of the same color through it?
Hello Mr. H, how is the speed of the transmitted wave at 7:48 greater than the incident and reflected wave even though the wave is entering a less dense material, becuase earlier you said that sound travels fastest in materials with highest density, therefore if in this case the wave is entering a less dense material shouldn't the velocity (speed) be less than earlier???
If all other things are equal, waves travel fastest in a less dense medium
hi mr h thanks
You are welcome
I was cooked in my physics class til you came along you explain stuff in a way I understand.
How does one figure out the value of v? Is that ever something a student is asked to find?
An occasional question. Use v = (3.0 x 10^8) / n n= index of refraction
@@PhysicsclassroomVideos thank you
You are Amaaaazing and this channel should have 4 million subscribers 👏👏👏👏👏👏👏👏👏✨✨✨✨✨✨✨✨
Wow! Thanks for the applause
WE ARE HAVING AN EXAM ABOUT THIS THING TOMORROW! PLEASE GIVE ME YOUR BRAIN JUST FOR TOMORROW HAHAHAHA KIDDING. THANK YOU SM, IM GATEKEEPING THIS YT CHANNEL. OUR TEACHER JUST TAUGHT US HOW TO SOLVE IT USING THE "SHIFT SOLVE" IN CALCULATOR, LIKE HELLOOO?😓 THANK YOU SM SIR❤
I hope it went well.
You are amazing (the best explanation of color pigment and light) 🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩
Thank you john physics
the ending tho hahaha thank you sir❤
Hey rockstar thanks like always
Always welcome
Mr. H, how can the force of gravity and the opposite force be the same when the object is moving upwards, shouldn't we overcome gravity to move up, because if net force is zero then how can we be moving?
If an object is in motion and the forces are balanced, then the object continues moving at constant speed. Put another way, a balance of forces doesn't mean the object is not moving. It only means the object is not accelerating.
you are a rockstar mr. h
this is crystal clear. God Bless physics classroooooooooooooooooooooooom. you gotta believe physics when you see the things Mr. H does
Glad it helped
love this thank you
You are so welcome!
very nice video, really easy to follow! :D
Glad you liked it!
This actually helps a lot! Thank you Mr. H.
Happy to help!
8:15 is perfect
Yep. Good summary.
Very well explained. Thanks indeed.
You are welcome!
Thank you for the education
i didn't understand is there any full video explaining this
@user-hz8vt8yr2o see our Refraction and lenses playlist.
@@PhysicsclassroomVideos thank u
Studying for 11th grade physics next school year, this is helping a lot! Thanks Mr. H!!!
So glad it's helping. We'll be here all year. Come back for more help when you need it.
Mr. H you are the first person who is able to explain physics to me and i thank you from all of my heart. I will share this channel as much as possible so that other people like me can get help as well. p.s. you are a rockstar.
Thanks for your very kind words and thanks for sharing.
mr. h you are a rockstar
Understanding Newton's Law of Universal Gravitation is crucial for grasping the fundamental principles that govern the motion of objects in the universe. This video lesson offers a clear and concise explanation of the Universal Gravitation equation and provides practical examples that make the concept easier to understand and apply. By dedicating just 12 minutes to this lesson, students can approach their next test or quiz with confidence, equipped with the knowledge needed to tackle a variety of problems related to gravitational forces."
Fantastic video, Mr. H! The way you broke down the Universal Gravitation equation was incredibly clear and thorough. Your step-by-step approach, especially with the four example problems, made it so much easier to grasp the concepts. I feel much more confident tackling my next test or quiz after watching this. Thanks for such a detailed explanation that really solidified my understanding!"
Wow, thanks!
On 9:29 how did you determine the F net?
I am lost in the sample question AT 6:20. Where did you get the weight of the earth and the moon? Is the weight of the moon and earth is it something that we have to memorize?
Nope. Don't memorize. What you learn is that Weight= mass *g where g is ~10 N/kg on Earth and that weight is another name for force of gravity. Then you take what you learn, read the problem, and answer the question by applying the learning.
Application: Given: mass = 2 kg and Fgrav on moon is 1/6 of Earth On Earth: weight =2*10=20 N On moon: weight =(1/6)*(20 N)
i fuck with this video HEAVY. I learned a lot :D
omg why did i only find ur video now... i couldnt understand this the whole time and after watching ur video i could completely understand thanks so much!
@@cappybaraeats I'm glad it helped so much
Should be able to create light from static can we store it
thanksss
thank you
thank you!!
thank you sir
I found this quite helpful. Thx
He's so calm yet impactful...am gonna definitely remember this during tomorrow's exam
