Hello shitanshu sir, you're doing a great job. This video was very helpful in clearing my concepts. Thank you. Looking forward to learn more.
Thanks for the appreciation.
mam I have a doubt... in first slide in case of "y" you told acceleration is -g but in second slide in case of "y" u told acceleration is g... How???

Hi Arpita, you doubt is very genuine. Read carefully, you have the power to decide your own sign convention. Just stick to them and you'll get answer according to those sign conventions. In the first case, I've taken downwards as - and upward as + so, g and h both are negative. In the next slide, I chose downward as + to simplify the equation and got the answer accordingly.

So, choose your sign convention at the beginning of a question and stick to it while assigning signs to all quantities to get the correct answer.

thanks for clearing concept
Mam i need assistance .. plz help
i have a doubt, agar first case mei projectile ko initial velocity de rahe hain to usko acceleration bhi milega qki initial velocity can be provided by means of force and agar force hai to acceleration to hoga hi??? to why in the equation of s(x) we put a=0??

We don't consider the cause of motion, we just stay focused to the motion. Ek baar projectile jab move karne lagegi kisi velocity se, us motion ke doraan uspe koi force nahi lagega x direction mein, so x direction mein acceleration zero hoga, ya hum keh sakte hai u=v for motion of a projectile in x direction.
