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 ✌️

please mark it as brainliest ❤️

Answer 2

Answer..

Velocity is a term which is used to define the rate of change of its position with respect to time.

In easy language velocity of a body is the distance travelled by it per unit time in a given direction.

More info

• SI unit of velocity is m/s

• It is a vector (means it has both direction and magnitude ) quantity.

• Formula

$v = \frac{displacement}{time \: taken} \: \: \: \: or \: \: \: \: \: v = \frac{s}{t}$

Here v = velocity of a body

s = displacement of the body

t time taken

• It can also be find through the first equation of motion i.e

$v = \: u \: + \: at$

• The direction of velocity is the same as the direction of displacement of a body

• The difference between speed and velocity is that the speed doesn't have direction whereas the velocity has
