ایک گیند عمودی طور پر اوپر کی طرف پھینکی جاتی ہے۔ جب گیند اپنی زیادہ سے زیادہ اونچائی تک پہنچ جاتی ہے تو اس کی رفتار کتنی ہوتی ہے؟
Explanation

 When a ball is thrown vertically upwards, its velocity decreases as it rises due to gravity.

At the maximum height, the velocity becomes zero before it starts to fall back down.
