Question

what is Velocity????​

Answer 1

ㅤㅤㅤㅤㅤ$\Large{\underline{\red{\mathbb{ANSWER :}}}}$

➾ What is velocity ?

➛ Velocity is defined as rate of change of displacement or displacement per unit time. It is a vector quantity. SI unit of velocity is m/s.

$\boxed{\sf{Velocity\ =\ \dfrac{Displacement}{Time}}}$

• Instantaneous velocity is denoted by :

$\displaystyle \longrightarrow \sf{v \: = \: \Delta_{t \to 0} \dfrac{\Delta s}{\Delta t}}$

ㅤㅤㅤㅤㅤㅤㅤㅤ

$\longrightarrow \sf{v = \dfrac{ds}{dt}}$

_______________________

Equations of motion are :

➺ v = u + at

➺ s = ut + ½at²

➺ v² - u² = 2as

Where,

• v is final velocity.
• u is initial velocity.
• s is distance.
• a is acceleration.
• t is Time interval.
