This is incredibly helpful. Thank you for taking the time to choose great examples, show everything in well designed animations, and discuss the topic in a complete yet succinct manner.

How did our fathers do engineering without YouTube ??😭😭😂

[zandiviljoen]

these help so much!! mostly because unlike the fundamental or preliminary problems, the answers in the book don't include the steps so if you have a small mistkake it takes ages sometimes to find it because there are so many steps.. thank you sir and bless you!! appreciation all the way from South Africa💛

[Scammer...]

Best explanation, but i am always here day before quiz or exam😅

[ahmedtareq]

Can't believe that you made everything that easy!!!, Best content ever made about dynamics on YouTube

[austin]

Would you ever consider making a Thermodynamics set of videos? I'm taking it next semester and your dynamics videos helped me so much

[Bob-myjy]

beautiful! I really liked the presentation and the way of writing it all down( the details ). Im glad I found this

Hi, thank you so much for creating this video. I have a question of the pulley problem - why is the acceleration of B downward? won't it be moving upward?

[driesvanranst]

For finding 'a' in the second example, you use a kinematic equation. However, for this equation to be valid, 'a' has to be constant. How do you know 'a' is going to be constant?

Hello . Your videos are very helpful . Can you please make videos on magnetism ? Thanks in advance .

[mebawubeshet]

for the last problem why do not we just substitute s =0, 2m to find the acceleration and use the constant acceleration equation s=vˆ2/2a to find the velocity

[kwtr]

For the last problem at 12:00, why we cannot substitute s=0.2m at that step and calculate acceleration? I'm aware that this produces the wrong answer but I don't understand why.

[kingBasa]

In the second problem, why did we put cos30 as the angle at which the weight is inclined instead of sine 30

[羅小悅]

Hey, I got a question. How do you identify whether it is sin or cos for the x and y component for force p? Thank you in advance

[jesussaquin]

For F=ma is acceleration always taken to be positive (9.8m/s^2)? Does it depend on our chosen axis?

[e-nes]

ı dont understand question at 10.56. why Fy=0 firstly?

[marielhagutin]

the pulley problem where you just show the answers on a of A and a of B and T didn't show the process, please show the process

[Minion-cqzx]

Why you used second equation of motion in second example to find acceleration when acceleration is not constant???

[ghadeeralharbi]

This channel is god sent, thank you 🙏🏻

Great video. for the 7:30 problem, how did you find the angle for W, I'm struggling to understand that
