      Hi Flanner πŸ‘‹ – you’re very welcome thank you for the lovely comment too!!

  • XXGraceAlexia FashionistaXX 2 years ago

    Thank you very much! I loved it I enjoyed the colourful diagrams, and the detail and the Information was short and simple, I’m in year 10 now that really helped for my new Science topic , which was work done and power πŸ˜‰πŸ˜‡πŸ˜„πŸ˜πŸ€©πŸ‘πŸ½πŸ‘©πŸ½πŸ‘ΈπŸ½πŸ™‹πŸ½β€β™€οΈπŸ‘‘πŸŒˆπŸ’«βœ¨πŸ’ŽπŸŽ‰πŸŽ‰πŸ“©πŸ“ˆπŸ“ˆπŸ“šπŸ“šπŸ“”πŸ“”πŸ“πŸ“πŸ“πŸ“πŸ“πŸ“–πŸ“–πŸ“–πŸ‡¬πŸ‡§

      Hi Grace! Thanks for the amazing comment – so happy it was useful to you, and good luck with all your work!!

  • Unknownlink0 2 years ago

    I thought energy can be transferred out and in in a closed system but mass cant travel out? btw im not sure if im right im no where near my gcse’s

    • Cognito 2 years ago

      Not quite – neither energy nor mass can enter or leave a perfectly closed system πŸ™‚

    Do you do any tutoring sir?

  • Saira 2 years ago

    Thanks dude, you are better than my two useless science teachers. Keep up the good work I hope you get noticed by more people ✊🏻πŸ₯°πŸ˜Œ

    • Cognito 2 years ago

      Thank you Jimins! Really happy the vids are helping you out πŸ™Œ

  • Jenkins Family 2 years ago

    amazing!!! i have a tripple science exam in a few weeks, do you cover anymore topics ,like density?x

    • Cognito 2 years ago

      Hey thanks for the lovely comment! We are in the process of releasing the rest of the videos! I don’t think density will be covered in time for your exam I’m afraid. But the whole of triple physics/chem/bio will all be ready for the 2020 GCSEs πŸ™‚

    • Jenkins Family 2 years ago

      okay thank you so much! :))

  • Jagjeet Kandohla 2 years ago

    science teachers at school are awful but at least your here!!

  • Michael Preston 2 years ago

    We are supposed to have moved away from the ideas of “forms” of energy.
    It’s not complete for AQA; there are 4 transfers of energy and 8 stores (6 relevant to the exam).

    Love the videos in general but this unfortunately this has missed a lot of the key teaching ideas behind the stores and transfers model of energy.

    • Cognito 2 years ago

      Hi Michael, thanks for the advice, we will bear it in mind for future videos! This video is just meant to be an overview of the different ways that energy is stored and transferred – so that students can better understand all the energy changes involved when a system changes.

      We cover more details on the stores like kinetic energy, gravitational potential energy etc and the methods of transfer like by heating (conduction etc) and mechanically (work done) in other videos.

    • Michael Preston 2 years ago

      ​@Cognito No problem. I do actually really like these videos. I show them in my lessons and/or as homework as I would struggle to provide such an intuitive, visual explanation with awesome visuals.

      This topic is annoying generally and it’s quite difficult to get the language right – electrical energy is particularly annoying as there’s no such thing as an electrical store.

    • Cognito 2 years ago

      Yeah I know, it’s a pain to explain things fully when students only need to know a limited amount for the course. Thank you for the feedback though – if you ever have any thoughts on how we could make them better or more useful, please do get in touch!

  • Vasanth S 2 years ago

    Just now I discovered your channel and I’m very much impressed to see your quality content. I’m Vasanth from India studying for NEET Examination(Medical Entrance Exam), I’m glad that I have found your channel today, I’m going to watch all the videos even though GCSE is quite different than CBSE(Indian Syllabus). Thanks for the video buddy. Really Great πŸ‘πŸ»

    • Cognito 2 years ago

      Hi Vasanth, thanks for the comment mate. Really glad you’re finding the videos useful and good luck with your NEET, I’m sure you’ll ace it πŸ™Œ
