[@Cognitoedu]

If you’d like to practise what's covered in this video, check out the lesson on the Cognito platform - cognitoedu.org/coursesubtopic/p2-gcse-aqa-h-t_3.08. The platform’s totally free, and has been built to make learning and revision as easy as possible. The main features are: - Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown. - Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on. - Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like. - A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts. - A comprehensive bank of past exam papers, organised both by year, and also by topic.

the explanations are really good...it helps a lot, thanks

[@Cognitoedu]

Thanks Anaum, glad it could help 👍

[@awesomedoshi5753]

Thank you so much for all of your videos. They are extremely informative, and cover most of my syllabus.

cant thank him enough

[@muhammadpatel5977]

Cognito, can you also do the triple science chapters as well

[@Cognitoedu]

Hi Muhammad, yes mate they’ll be following the physics double science material :) they’ll be released in plenty of time for the 2020 exams 🙌

Is all of these combined science or is it for grade 10 or what exactly

[@Cognitoedu]

Hi Ali thanks for the comment, yeah the videos cover both triple and double science material! Not all of it’s been released yet though so you may find a few topics haven’t been released at this time. Hope this helps

I cannot find the video for Newtons 2nd law Can you help me?

this is the video name (GCSE Physics - Newtons First and Second Laws #56)

[@abenayasuntharakumaran6194]

won't the 100N force and the other 100N force cancel out and cause no acceleration?

[@sarahfahdah5008]

action and reaction force pairs don't cancel because they act on different objects. The person is pushing on the box (the box is object 1) and the box is pushing back on the person (the person is object 2). Forces can cancel only if they act on the same object. acceleration depends on the formula: force = mass* acceleration. F= ma can be rearranged to: a= F/m. So if the person is pushing on the box with 100N of force , but the box weighs 1000000 kg to work out the acceleration of the box you would do 100 N/1000000 Kg.. This means the box would accelerate but it would hardly be noticeable. So to summarise, the acceleration depends on the mass.

nooo I wish u could help I feel so bad

[@nabiha5942]

NEED A LITTLE HELP HERE... 0:54 you said that either of them can move..right? sooo what if the mass of both is 60kg... and if are exerting the same force of 30N... then?

[@riyapatil3137]

I think none would move because you will require a higher amount of force to bring about movement and overcome the inertia of the object you want to move..this is what I think but confirm with someone else as well

[@aaisharahman9883]

Is that AQA or?

[@zainrizwanthegoat]

the description says that it is for all exam boards

[@jizzalhaddad2843]

Bru my teacher took a whole lesson on this bro did it in 2 mins

[@ChefDyYT]

Exactly, at this point we are wasting our time

[@codex1758]

If I push onto a wall then why do I not go back lol

[@anmzn.]

you do, do it hard enough with your feet positioned together and stand close to the wall. if one is behind the other then any force that is relayed onto you is absorbed and relayed onto the ground instead of pushing your body back noticeably

[@k3nsh0.]

Do a push up mate💀on the way back up you push downwards
