Kinematics 20 - Sign convention for motion under gravity

Motion under gravity implies motion under the influence of earth near the surface so that the particle has a constant downward acceleration due to gravity (g).
Positive direction for vertical axis is defined arbitrarily. If upward direction is taken positive then acceleration is a= -g; and if the downward direction is taken positive then acceleration is a= +g.

Best explanation I got. Thank you so much sir. I would have lost my confidence in JEE exams, as I was unable to understand the sign convention. But you saved me. I'm grateful.

Sir S L Arora class11 ki book ke exemple 29 or 30 main g ka velue apke bataye geye ruls ko follow nehi Kar rahe hain

[vanshyadav]

Sir m 5 din se confuse tha negative or positive kab lu apke ek bar me hi smj agya thanks sir

[hasanziauddin]

Solvea siple example by upward motion and downward motion

[ezio]

Sir thank you so much now I will never forget this in my entire life

[THUNDER-ujrt]

Nothing was understood. How can we take -Y upwards ?plzz explain me sir or anyone ?🙏

Sir agar weight find karna hai to g negative lene pe weight negative aayega hamesha to kya kare

[tenzinengsel]

So gravitation is always Ahh so confusing, someone please explain me✨

[gloryjaw]

Sir agar koi 7 m/s ki speed se bhaag raha hai toh uski speed ko gravity ki acceleration se fark padega??

[medico]

Totally Confusing Thank uh for wasting my time

[mrrohitsingh]

Apke rules kisi bhi questions mai apply ni hore hai
