Question

what do you mean by velocity​

Answer 1

Explanation:

the rate of change of position that is rate of change In displacement with time is called velocity

⭐it is a vector quantity

⭐its dimension are m0 L1 t -1

⭐unit is metre per second ( SI unit)

⭐centimetre per second ( CGS unit)

hope it works ✌️

Answer 2

Answer:

The rate of change of displacement of an object is a velocity of that object.

Some properties of velocity are:

• It is vector quantity which means it has both magnitude as well as direction.
• S.I. unit of velocity is m sec⁻¹
• The velocity of an object can be negative, positive, or equal to zero.
• $Formula \ of \ velocity=\frac{total \ displacement}{total \ time}$
• $Dimensional \ Formula \ of \ velocity=\left[ M^{0}L^{1} T^{-1} \right]$
• $v=\frac{ds}{dt}$

Hope it is clear to you.
