The Physics Classroom provides easy-to-understand and ready-to-use learning resources, activities and curriculum to support the efforts of students, teachers and classrooms.
The odd numbers of harmonics here…is why the clarinet has so confusing fingering across the octave. Every other woodwind instrument has similar fingering above/below the octave.
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
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 )..
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.
@@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.
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???
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❤
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.
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.
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."
