I'm glad that this explanation has helped you. Wishing you all the best for your SOF Olympiad! :)

Thanks! Hopefully the explanations in my videos are clear too :)

Thank you for your feedback. There is no error in the video, the arrows are in the correct direction. Please read the pinned comment for my explanation. I have explained a common misconception that students have in analysing such questions.

You're most welcome! Thanks for your encouragement :)

Thank you for your encouragement! All the best for your studies! 🙂

Thank you! All the best for your studies :)

There is no conceptual error in my video. The 3rd and 4th cases are deliberately included to highlight a common conceptual error of students and teach them how to analyse such questions. The misunderstanding is on the student's part. If they take time to read my explanations in the comments, they will understand it. The responsibility to learn and clarify any doubts rests on the students. I am most happy to explain to anyone who leaves a query in the comments section. My RUclips analytics show that this video has been uploaded to several educational institutions' websites. I also know of teachers who have shown this in class. This video is valued by educators in different countries as a useful teaching resource. The many comments left by students also show that they have appreciated my explanations. I will not deprive many students of learning simply because a few do not make the effort to clarify their own misunderstanding.

Wow, that's interesting! Thanks for sharing this insight :) I found this explanation with illustrations of the airflow online: www.sciencenews.org/article/dandelion-seeds-create-bizarre-whirlpool-air-fly

Are you referring to how to draw light rays passing through a lens? I have a video here explaining how to draw the ray diagrams for a thin convex lens: ruclips.net/video/fT-CAcuMMR0/видео.html

You are most welcome :)

Thank you for your encouragement! Hope that you found it helpful :)

Thank you! I hope that this has been helpful for you :)

Thank you for your kind words of encouragement! I'm glad to be of help. All the best for your studies :)

Thank you for your encouragement! I'm glad that this has helped you to understand the concepts better :) I only teach Chemistry up to Lower Secondary level, so I won't be able to make Chemistry videos that are suitable for your level. I will continue to share Physics videos like these when I have time to make them. All the best for your studies :)

@@ExpSci Thank you 🤩

You're welcome :)

Thank you for your encouragement! 🙂I'm quite busy with teaching, but I will try to make some more videos when I have time. I have another video explaining about Lenses here, hope that you will find it helpful too 🙂 ruclips.net/video/fT-CAcuMMR0/видео.html

@@ExpSci Thank you. You will certainly help all those who need extra help❤️

Thanks for your encouragement! Glad you enjoyed the video :)

Thanks for your feedback :) Are you referring to Scenario 3 and 4 from 2:46 onward? (the 2nd scenario is constant motion since the dots are evenly spaced). For Scenarios 3 and 4, the cars are moving in opposite directions, so the Ticker Tape readings are also read in opposite directions, starting with the 1st dot immediately behind each car. For Scenario 3, the dots are read from right to left, so the spacing decreases and the car is decelerating. For Scenario 4, the dots are read from left to right, so the spacing increases and the car is accelerating. Please see my explanation in the pinned comment for more details. Thanks :)

Thanks for your encouragement :) I'm glad that this video has helped you ☺

I'm glad that it was helpful for you :) Thank you for your encouragement :)

Water is a compound, because it is made up of Oxygen and Hydrogen atoms which are chemically combined in a fixed proportion (1 Oxygen to 2 hydrogen atoms). Mixtures can be separated using physical means (eg a salt solution can be separated into salt and water using distillation), but compounds can only be separated using chemical methods. In this experiment, an electric current is used to separate water into its component elements :)

Thank you for your encouragement! All the best for your studies :)

谢谢！我祝你学业成功👍

Thanks for your encouragement! All the best for your studies :) I have just uploaded a new video explaining about images formed by a converging lens. Not sure if you need to learn this as well? ruclips.net/video/fT-CAcuMMR0/видео.html

@@ExpSci you're the best and so are your videos

Thank you! :)

I am so glad that you have found it helpful :) Please let me know if there are other topics that you need help with. If I have time to make the video, I will share it. All the best for your studies!

Hi Angus, thanks for asking :) Please feel free to do so :) Sorry for my late reply, I just saw your message.

Thanks for your encouragement! I'm glad that you have found this helpful :)

I'm so glad that you found this helpful! All the best in your studies :)

Thanks! Hope you've found this helpful :)

@@MarcablancaP Thank you! :)

You're most welcome :) All the best for your studies!

You're most welcome 😊

Yes, many Physics students struggle with the topic of Kinematics. Do let me know which part of the video you need further explanation with and I will try to explain in the comments section :)

You're most welcome 🙂Thank you for watching!

Thank you! This is one of my favourite topics to teach as well :)

Yes! We can learn so much from the designs in nature :) All the best in your journey of discovery!

Thanks 🤗

You're most welcome :)

Thank you for your encouragement :)

I'm glad that it has been helpful :)

Thanks dear teacher it's a very good interpretation. Appreciate your support.

Thanks Shanthi, I'm most happy to help :) All the best for your studies!

Was kinda confused but this cleared things up thank you

@@malihnamps I'm glad this has helped 🙂

I think u messed up the arrows. At the 3rd scenario, arrow shoul be right to left and in the fourth scene, arrow should have been left to right

Thank you for your feedback :) I believe that you are referring to the diagram at 2:46. I should have indicated the position of the needle which made the markings on the diagram for greater clarity (The needle is shown around 1:08 of the video). In the 3rd scenario, the 1st dot made is the one nearest the car, then the car pulls the paper through the ticker tape machine, so we read the dots from right to left due to the direction that the car is moving. Since the distance between 1st & 2nd dot is large, the car was moving faster at the start. The last 2 dots are on the left of the tape and the distance between the dots is less, so the car moved slower and pulled the paper through more slowly. Thus, for Case 3, the car started out fast but ended up slow, so it's decelerating. For the 4th scenario, since the car is moving from right to left, we read the markings from left to right instead (as we imagine that the paper is being pulled through the machine towards the left now). The 1st dot is immediately behind the car on the left, and the distance between 1st 2 dots is small. The last 2 dots are on the right of the tape and the distance between them is large, so car started off slow but end up fast. Therefore, it is accelerating. I hope that this explanation helps to clarify :)

@@ExpSci OHHHHHHHH THANKS THIS CLEARED UP THINGS

@@cactihead I am glad that this helped :)
