what is meant by velocity
dynamicmayuri:
Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocityis called "speed", being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1).

1 )velocity means the speed of something in a given direction .
2)Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second(m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude. The direction of a velocity vector can be expressed in various ways, depending on the number of dimensions involved.
Hope it will help you
I have given two meanings of velocity U can refer it

Answer:
Velocity :-
Velocity is given as displacement per unit time .
Velocity is a vector quantity
The SI unit is m/s
formula of velocity : -
v = S / t
here ,
v is velocity
S is net displacement
t is time taken .
Hope it helped and please mark as brainliest:)
