bruh you guys lucky, im yr10 and everything goes back to normal next year so we dont get a easy exam sheets this is bs XDD

You are literally the best person on here for science. I am doing higher and physics is my weakest. These videos really help. Thank you.

so hows physics after 2 years

How’s physics after 4 years?

4 years and 7 months

so how's physics after 5 years?

[@supergirlygirl2970]

you are literally the reason why I have the motivation to carry on revising I love you sm thank you for everything

[@anonymousyouth7479]

I hope you're really relaxing sir, soaking your feet and probably won't read this comment JUST YET- A well-deserved break, thank you for helping us students out there constantly non-stop for more than a year, including christmas day! Seriously, Thank you for everything

So so useful! If only my teachers were like you!

[@XtrimB]

you make these videos as soon as i come across them in school and want to revise at home. Making my life so easy. Thanks a lot

[@ArikCool]

How is it even possible he explains everything in a short time and easily?

when it takes teachers 4 lessons and i still never get it

[@leagallien-currier6539]

honestly this dude is a legend

[@um4R_67]

bro this guy taught me this topic in 5 mins and my set 1 teacher couldnt do it in an hour it goes to show that set 1 teachers are overrated af and dont care abt students thta much bc they think they can "rely on themselves."

100000000000% You are the best teacher Mr Donnelly

[@romxsayeppie]

sir your TRULY A BLESSING!!

[@Freesciencelessons]

Thank you. I appreciate your comment.

[@Celeste_51]

I’m confused at how you managed to rearrange the equation at 2:58

[@2007unknown]

Same

[@beanie2154]

he added u^2 to both sides to remove it from the left

[@jayfrith8085]

you probably won't see this message but will you be making a level physics videos at some point? they will be very very useful for me next year 😁

[@AhmedMohamed-rm3lz]

why dont you come to teach us in our school ?! :(

[@bangtansquarter6278]

Sir, when you say CONSTANT RATE, do you mean a straight line??? For acceleration, can you please tell me the difference between the two equations, and when to know when to use them?

[@seresdaoud3171]

you use the first equation when time is given to you. You use the second one when it's not given to you.

Hi science guy when do you think you will start the biology paper 2 questions on variation and evolution needing your videos desperately 🤓😩😫

Can’t thank you enough❤️❤️

[@zainm217]

3:02 I'm abysmal at rearranging equations like this. :( oh man I need an algebra crash course

[@3mb936]

so blessed to have the equation sheet in the 2023 exams 😭

[@avinashjayachandar7965]

sir how do you get 400 (3:22)

[@Freesciencelessons]

U is the initial velocity which is 20 m/s. U squared is 400.

[@avinashjayachandar7965]

Thank you very much

[@hallabajwa9325]

Will all the revision guides be out in time for the exams?

[@angeltiffany5617]

It's easier to understand thanks

[@BlazeGaming1905]

Do you need to know the suvat equations?

[@Sheena1234ization]

I hate those so much

[@ipodzonly123]

It's given in the equation sheet for aqa

[@viralfooty4844]

same

[@ala0284]

They’re given even though our physics teacher spent 2 months trying to get us to learn them in year 9

[@FlixRacing]

Thank you!

[@domlapss]

No Problem

[@HiMeee993]

”you won't be given the equation in the exam so you need to remember it” Me: *laughs in 2023*

[@rodoshik.s.8122]

When you say lower terminal velocity, does it mean the person stops and accelerates at a constant velocity at a quicker or slower rate?

[@ehsanbattye2203]

Anyone else get a honey ad telling you to watch this video later a day before your tests?

[@znaltxt]

11pm revising for gsces🥰😂 but in 2022!!

[@Gmoney-Matthew7verse21]

I have a question, will the equation for uniform acceleration be arranged for you in the exam

[@YC-iw2re]

Will the 1-9 videos be finished before GCSEs start?

[@syedjunaid7846]

They will be done by April 2018 I think

[@Sheena1234ization]

Will you do monoclonal aniti biotics?

[@syedjunaid7846]

Use your own initiative and check his Biology playlist.

[@praisemutoko3175]

Thanks a lot.

[@jadjanho5001]

god bless your soul

[@rebeccas5713]

Have you/ would you ever try skydiving, sir?

[@priya200328]

Why do you square root your answer?? (3:20)

[@lioncubden]

because it's v2 = 900 so to get v you need to square root 900 which gives 30m/s

[@nadimesalehin1770]

laith E thank u so much, I was so lost on that part

[@anaskhalid297]

When there is a square on one side of = then it is must to put square root on the other side to get the answer

[@ala0284]

That’s just basic maths

[@edd1482]

did u pass

[@Spongecake420]

Hi. If the question asks to calculate deceleration, is the answer positive or negative? Thanks

[@anonymousyouth7479]

It will be negative.

[@plutosstrawberries]

could this video be considered SUVAT equations?

[@sachinsathiyaamoorthy2477]

I think suvat has a few different formulas as well as this. Im just starting it, but I think that its there.

[@fishynighcorelover8988]

great!!!!!

[@hocuspocusdiddlydocus5290]

Sir, how do we know which acceleration equation to use?

[@Freesciencelessons]

Often in the exam, they will ask you to write the equation that you need. For example, write down the equation that links the force applied to an object to the object's mass and acceleration.

[@kkkkkkkk885]

These videos are very useful for me and I can understand them very well 👍

[@rix_1723]

can someone define me the terminal velocity in one simple sentence? Thanks

[@Freesciencelessons]

The constant velocity that occurs when the forward (or downwards) force is balanced by the resistive force (eg air resistance), to produce a resultant force of zero.

[@rix_1723]

@@Freesciencelessons thanks

[@harrydragon23]

How to rearrange the equation to calculate initial velocity this is urgent please help!

[@priya200328]

Will you be given the equation in the exam?

[@Freesciencelessons]

Yes that equation is given in the exam.

[@redxgaming7760]

Do you need to know this in year 9??

[@umalmohammed6942]

I didn’t know this in year 9 and Im trying to learn it now in year 10 it’s better to learn it now then stress later haha

[@priya200328]

Why some times the acceleration = v - u / t and not a = v² - u² / t ??

[@ML-yz2pu]

the second equation is only when the acceleration is at a constant rate (e.g on a graph the line is straight not curved)

[@peachesandcream827]

@@ML-yz2pu will they tell us in the exam which equation to use? I find it hard to figure which I should be using based on word/scenario based questions

[@Name7.62]

@@peachesandcream827 You will be able to work it out from the question and the values they give you. For example, if it asks for distance travelled and it gives you an acceleration value- you use the equations given in this video.

[@brendonoreilly9593]

I like how he says try not to worry, but I'm far too thick not to.
