GCSE Physics - Acceleration #52

[@solaymanbhuiyan3993]

Cognito and freesciencelesson videos both make topics easy, but Cognito is on another level for quality and info.

[@sakadagoat2864]

But freesciencelessons is still the 🐐 😂no one will ever be better🤣

you seriously deserve more recognition you're videos are the literal definition of amazing!

Thank you! Amazing how I can fully understand a topic from a five minute video here, and not understand a thing from 2 hours worth of lesson from school

[@ondre.j]

i learn so much more in a 5 min video compared to a 1 hour lesson

I'm so grateful for your videos, like i was doing a question that i did not understand one bit but i watched your video and i did it right. i have test tomorrow and i was panicking about this but luckily I watched your video.

Thank you so much for this explanation, I have my physics exam tomorrow and never understood this equation. If it comes up then I can only answer it from this video

[@TehreemHaroonTaj]

i was watching videos of hours and hours to understand this topic but when i listened Cognito's lesson's it explained everything in under 10 minutes

[@supercoeur100]

Great video! This topic is very confusing so thanks very much!

[@mehradkarimi4877]

that was awesome at least i learned something

[@Sara-zm1gp]

3:09 but the distance is unknown in the question that this equation was applied to. We were given the final velocity. Does that mean that the second equation is used whenever anything other than time is known?

[@naveensundar4765]

Yup exactly

[@truestriver6512]

thanks sooo much cant believe i just found ur channel now

[@arifsami4353]

Bro Is a life saver frr

[@trqst]

quick question, in the second equation. Why is there a 2 in the beginning if there wasn't any in the first one?

[@syedabdullah6178]

Damn excellent vid

[@wooooo3838]

1:40 can someone explain why we divid it by 5? Thx!

[@CashoMuxsinSalax]

Because its the formula for it.a=v-u over 5 so you have to divide it by 5

[@CashoMuxsinSalax]

Because that's the time

[@raaafn874]

Hi. Your videos are incredibly useful and make me euphoric. My question is that, at 4:50 do you need to know that acceleration for gravity is 9.8m/s squared? please tell me as I am nonplussed

[@nastery440]

i think so, because its just a fact you need to the speed of gravity and a lot of people do

[@ashwaqmunif7700]

if the question doesn't give you a specific acceleration use earths acceleration yes for the best but sometimes exams will give you earths acceleration mostly

[@MeghanMcgoldrick-p3y]

have a uni exam tm for zoology and never understood this equation, could give you a big fat kiss babes xox

[@Qasimodoz]

The letter "S" means displacement and since acceleration is a vector quantity, shouldn't it be displacement instead of distance??

[@bluechronicles459]

[@andrewcampbellsmith1880]

Hi, thanks for the great video. Question please: at 1:42 the calculation of acceleration is 4 m/s 2 - why does the 4 m/s become squared - 4 m/s 2 ? Thanks

[@wonderwhy010]

It’s the unit of acceleration meter per second square

[@XarSir.]

Amazing video

[@SourojaGhosh]

s = ut + 1/2 * at square is not there...

Hey I follow you guys every subject and they are super easy and cool. Can you plz start a further maths channel too😊

heyyy, i am not sure wether or not they have a channel for other subjects but they do upload math videos too.

Morning of exam day 🎉

[@SUKUMARSUDERSHANAM]

Thing is an awesome course

[@HAM-re4ji]

4:17 From where you get the 9.8.?

[@kleesbombs]

thats because it is a known fact that free fall on earth is 9.8m/s squared, so u need to memerise this fact (sometimes it is rounded to 10m/s squared but yeah)

[@kaitlynwylds5932]

It's the gravitational force, because the ball is being dropped you need to apply gravity to the ball!

[@Successcomesonce]

Can we round of the acceleration of free fall from 9.8m/s ² to 10m/s²

[@Successcomesonce]

@Linda Abdeen dude I got 2 out of 20 now! Thanx btw 😂😂

[@ashwaqmunif7700]

that can change alot but some exams well expect the accurate acceleration

[@solaymanbhuiyan3993]

Those who dislike these videos are thick-heads who don't want to grasp the main details, and sometimes a bit of extra info; they like freesciencelessons, which always ditches some important info.

​@@vibes.5470 ​ Looking back now, I admit what I said was me ranting out overhyped opinions. But, you got to admit, comparing freesciencelessons and Cognito at GCSE standard; is like comparing physics online and science shorts for A-level Physics revision.

very helpful i like 😀

[@SamT1N]

thanks for the great video.

[@yasiinshah9144]

How did you get the result of 49/19.6= 2.5 m?

[@nabiha5942]

umm....... that is simple division bro... dividing 49... not taking squared root.(if thats what confusing u)

[@ashwaqmunif7700]

because 7 squared - 0 is 49 / (earths acceleration * 2 = 19.6) so 49/19.6 = 2.5

[@nimco5922]

Cognito is THE 🐐

[@ThedementedoneXD]

Oml- third is so asthetic and amazing-

[@WilanderMascrenhas]

I have a doubt as acceleration is m/s squared. Shouldn't it be time x time in the first problem. 20/25....... Because acceleration = displacement/time x time. Sorry I'm new to physics. Any help would be much appreciated

[@justpeachy6450]

Tysm. Doing extra practicing last minute for a quiz

[@CutePrincess-tz7ds]

I still didn't get the - part where its negative and I didn't understand why do we multiply also why is m showed with s in the last question .

[@mayskhoujali3410]

4:16 how and why is it 9?

[@ashwaqmunif7700]

because thats earth acceleration and if exams are saying a object is falling without giving you a specific acceleration it will be set auto to earths acceleration which is 9.8

[@alexandersalas1998]

Where did the 9.8 m/s2 came from?

[@kaitlynwylds5932]

9.8m/s2 is the gravitational force, any object that is falling or dropped has a force of gravity applied, meaning you need to include the acceleration of 9.8m/s2 (gravity)

[@mohamedjameel5391]

yo is the formula v2-u2/t=a same as v-u/t

[@ryantamehzabin4091]

4:55

[@Frogbuo2424]

we all are here cuz of our teachers that teach almost nothing in there whole lifes while cognito can teach generations of physcis in a week

[@llama_meg]

real

[@yiphone1334]

But I have a doubt can anyone clear it? In this formula-> 2as=V2_U2 how did we get 9.8m/s2 as acceleration

[@SweatXD]

see everything in earth accelartes at 9.8 m per second so thats the accelaration and in the formula u have to multiple the accelartion by 2 so he multiplied 9.8 by 2

[@nuhaminsolomon-o1d]

what curriculum are you teaching???

[@panic7703]

Mandem guess what i was driving my rs6 in germany it was so fast that i went faster than the speed of sound and crashed in a pole

[@GotLostUK]

yeah

[@krishverma2110]

so does it mean, any free falling object has an acceleration of 9.8?

[@crispybacon5061]

yes but most exams just say it is 10

[@ashwaqmunif7700]

well because earths gravity 9.8 but it can vary in exams to test your skills
