A very good video. Nice!!!

[@Isra-nv5nf]

Can you please include a document of the paper so I can do the questions along with the video

[@saraahmed632]

Hello, thank you for uploading these videos they are very helpful. I just have one question. For question 10a is the vertical component of the tension in the line different to the resultant force in the vertical direction?

[@saraahmed632]

Also, please could you do a video on questions relating to Archimedes principle. I would really appreciate it. :)

you should put the amount of marks on the question , it's easier to visualize what i need to do for some questions when i know how many marks ill get for it

Kinda confused about the question with the racecar... Aren't F=ma and F=mv/t basically the same equation but just different manifestations of Newton's 2nd Law? Since acceleration equals change in velocity per unit time, you're just replacing the 'a' in F=ma with 'change in velocity over time'. So therefore why is it acceptable to use the second equation if mass isn't constant but not acceptable to simply use F=ma?

[@burrowsphysics]

They both originate from F = d(mv)/dt but that equation only simplifies like you show to F = ma when m is a constant which is why you can take it out of the change expression d(mv). If m is not constant, you can't take it out of the change expression to make it md(v).

Ah awesome thanks!

Very nice

What exam board is this for?

[@burrowsphysics]

The questions are from AQA but the content is core to all of the boards
