I am writing Matric in June as an adult at 45 years old.. I have only from today to get all of this into my head. That is around 3 months only to get 6 subjects including Science and Maths into my head. :|
This is awesome! You are giving yourself a huge advantage for next year and you are making your life easier for next year :) Just a few hours per day will make a massive difference for you.
hey thanks so much i think i have a better understanding now ,but for the second question ,im noticing u used the time u got from the previous question and at school we are told not to use answers we got from previous questions because what if we are wrong ,so i would like to know how would i then determine the maximum height
How is the final velocity different from the initial velocity hence textbooks state that when an object is thrown upward the final and initial velocity are the same?
Hi Kevin!💙 I have a question. In Question A) I understand everything but what I don't get is that in the formula vf=vi + a × delta t *For Delta t, you didn't say t final - t initial, and then after that work your way through... So when we see "delta t" we don't need to expand it like that ? Let me know 😊
Oh yes but we do not need to worry to much about that. Sometimes textbooks, or even teachers switch this around. You can use delta y if you want though, it is technically MORE correct :)

Would you mind being my tutor, i don't mind paying 🥲
When I tell you that my life as a G12 student just became easier in minutes I'm not exaggerating 🥺😩Thank you for saving my highschool career! 💕
Melanin, I am so happy to have been able to help you! All the best :)
so tired rn but you made life so easy kev🤝🏼
Thank you so much this helped a lot
Glad it helped!
"if you're a cave man you would do it like this " 🤣🤣🤣🤣
Your videos are really helping me 🤩

Dam that is insane that you are doing this. Well done!!!!! :) And I wish you the absolute best!! :)
@@kevinmathscience Thanks, I need the wishes.. I really am way behind on the mathematics. So much to learn and remember with so little time.
it does make sense now and i do wish my teacher explained it this way 🥺😦
Matric 2022?who's studying in December?
This is awesome! You are giving yourself a huge advantage for next year and you are making your life easier for next year :)

As A grade 10 Im writing about this tommorow❤ This makes my studying much easier
How did we move from 10.8 to 5.2?
Why are we using delta x when calculating displacement while it's a vertical motion?
Right 😂
Kevin i calculated the maximum height but i used the 2nd equation is that fine ??

Hi Kevin, ain't we supposed to use delta y instead of x when we determine the maximum height? 6:05
Yes you can do that but they do not mind in the exams... Some learners use x and some use y :)
If displacement was going downwards would the displacement remain -ve?
1:34 if you are a cavemen😂😂😂

Let me know 😊
Yes technically we should expand but usually t initial is 0. So that is why I do not expand it.
@@kevinmathscienceif it was dropped initial time would still remain to be zero?
youre theeee best!!!!!
Thank you Mokgadi and all the best :)
And we are working for vertical?
Cool🥶
All the best Owami!
Sir i don't understand 9.8 thing .1 sec...2sec - what what like i don't get it☹
one question....who throws a ball upwards at 50 meters per second... that's half a kilometre fam
Can't you just divide the 50 m.s‐¹ by 9.8m.s‐² to get 5.1s
Yes but that ONLY works if initial velocity is 0.
vf = vi + at so if vi = 0, then we have vf = at and so t = vf/a :)
Isn't delta x horizontal?
Oh yes but we do not need to worry to much about that. Sometimes textbooks, or even teachers switch this around. You can use delta y if you want though, it is technically MORE correct :)
