What I honestly like about you sir is that u Don't complain like our teachers ..."u learnt that in previous grades" 😫 ...u just teach everything ♥️✨

[@MlungisiNkosi]

If you ever wanted the secret behind why people gravitate towards this channel... There it is!!! Thank you 🤗. Ill continue to do my best

[@nombusongubane5298]

These lessons are enjoyable thank you 👏🏻👏🏻👏🏻

[@clareiyer9429]

Hello sir, I just wanted to say thank you so much for these lessons. I had just gotten my physics exam mark back, and it was 91%, thanks to you sir🙌🙏

[@MlungisiNkosi]

Genius genius genius!!!

[@calvinbafshoe2626]

I'm glad your channel is growing sir. When I started following you, you only had 4k subscribers but now your subscribers have doubled in numbers. Keep up the good work!

[@MlungisiNkosi]

Thank you so much sir. I'm amazed at the testimonies that I keep hearing about the channel. We are called to be the light of the world and I honestly sought to exhibit that. I thank God for the growth. Thank you for being part of the family as well.

[@solvingexampapers]

Great lesson indeed! Let’s help fellow learners especially that they’re writing final exams soon, these lessons will surely benefit them. Good luck to all learners, watch these sciences lesson and you will pass with flying colors.

One of the amazing channel i have ever found thanks sir

[@tacochan8015]

For the second part of the problem at time 26:13 I got a different answer and I typed it in the exact same way. I got 683.79 N how did you get 571.44 N?

[@Aishwarya_0310]

I got the same.. I think sir miscalculated there.

Sir please must the G value always be used in all the calculations .

[@MlungisiNkosi]

Thank you. I will

[@ashenreaper1668]

hey sir, the answer i get is 683,79N. i have checked more than ten times but its giving me the same answer. Please assist me on that query.

[@MlungisiNkosi]

Will do

[@leratolaka2740]

When I calculated question 1.2 I got 683.79N not 571.44N

[@MlungisiNkosi]

I'll check if there is an error... It happens to the best of us. Thank you for understanding

[@michaelaroux9032]

I double triple checked.... I also got 683.79N

[@mihlasthembele9469]

I also got 6.859361641×10^-6 but ill also re check 👏👏

[@ashenreaper1668]

i am also getting the same answer. 683,79N

[@philaphuza47]

Meener the answer at 1.2 for the first problem question seems to be wrong i checked like 5 times and i remembered the question looked familiar from the Answer Series I checked there and my answer kwi calculator matched their answer .....Also for the second problem i attained 59 0000m as my answer ..i dont know if it's wrong cause Meneer's answer was different from mine

[@MlungisiNkosi]

Sometime I do make mistakes in my calculations. Thank you for pointing it out. The main thing is that you understand the concept and the process...

[@siphesihlebuthelezi9184]

Good morning Sir Nkosi, I would like to know, if the distance below the surface what do you have to do, is it then we subtract

[@tanyamv]

Sir my answers don't come out like yours in the calculator what mode are you on? For instance my Distance came out as 69....yours was 6.9

[@MlungisiNkosi]

I think the most important thing is that you understand the concept and less about the final answer. Nonetheless either one of us could have made an error. If it's was me, receive my sincere apologies

[@tshegofatsomangaba]

Am I correct to assume that for the ieb students out answers are different because the value of G on our formula sheet is 6.7… not 6.67…😅

[@thephilosophyofhorror]

Very good video. Thanks :)

[@uzochukwujoshua-t2e]

thanks you sir ,i enjoy this

[@MlungisiNkosi]

[@yolanda7560]

How do I setup mode on my calculator to do universal gravitation calculations correctly

[@MlungisiNkosi]

You don’t need to set up anything… Just make sure you use “EXP” button next to the “ANS” button to save time

[@lethubesalome3067]

dear sir when trying to calculate the distance above the earth's surface on the example 2. I got a different answer which was 59000 instead of the 594and something

[@MlungisiNkosi]

That’s fine

[@phuti3031]

Good Afternoon Sir can I please ask a question..if you dont mind ..... When someone is on the ground then they go up a mountain 6000m do we take that 60000m and add it to the radius of the earth ... If so why do we do that because they are practically still on earth

[@MlungisiNkosi]

Yes you do,,, I’ve covered that question in one of the past papers
