*My physics teacher made this look a lot complicated than it actually was thanks for clearing this up.*

The way I like to think about it is:

If the object is accelerating in the direction of tension: T > mg so T = mg + ma

If the object is accelerating in the opposite direction of tension: T < mg so T = mg - ma

Websites, school and textbooks gave no answer, this solved everything within the first minute. Thanks.

I’m literally doing engineering at uni right now but still using your videos as a review, thank u!

[floralynphea]

This channel is awesome! Deserves way more views and subs

[doaakhalid]

This just helped me clear my maths mechanics concept ...thanks

[AllanLovezGaming]

This is one of the best explanation I have seen so far on youtube and in school. Thank you so much!

[QuaternionPhysics]

Much more simpler than I had imagined. Thank you so much, explained it amazingly!

[eggxecution]

excellent! also my tip is that if acceleration is involved, I don't sum the forces to zero, I equate it to =ma which works because the 2nd law of motions states that if object accelerates, F is not = 0, instead it's =ma

The concept of tension gave me a lot of tension 😂😂😅😅 But now all me doubts regarding tension are cleared thnx a lot 👍👍

[DopeAK]

same way mv^2/r is a resultant for ma is also a resultant force, tension is acting opposite to the weight to T - mg = ma which can be rearranged into the equation, I find that to be easier to understand

Its informative and simple lecture.. Thank you very much 🙂

[tajmeeradookhan]

this is not as complicated as i thought it was. i just needed to understand the basics to be able to work the questions and you did a great job at making me understand. thanks a lot

I’m having a mechanics test tommrow to prep for my year 12 mocks this is really helping thank you I was wondering


where free fall is placed or what’s it under

thank you

[hoodahmed]

its easy if you think about it says the guy with a physics degree and a decade of teaching experience

[pariwartanshrestha]

Helped me a lot at the nick of a time.. Thanks myan

[joashbrijit]

I am no longer confused during physics and math lesson :)

[kyllel]

could you go over questions like the GCSE maths tutor does it would be more useful

[matteo]

Great video, but I’m a bit confused with some stuff at the end. If the lift is accelerating upwards, shouldn’t the forces acting up be bigger than the forces acting down, so shouldn’t it be T+ ma = mg

*What if a body is tied with rope on its right side and Lying on the Table. Then also tension actually acts towards the right side of the block* ?
