Question

what is meant by velocity

Answer 1

velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is 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).

Answer 2

HEYA!!
---------

✔Velocity can be defined as the Displacement of a body in a unit time.

✔Formula :- Displacement/time .

✨Simply we can say that the change in displacement with respect to time is called Velocity.

so it can also be written as dv/dt.

✔It is a vector quantity i,e it has both magnitude and direction .

✔It's units are m/s.

✔It's dimensions are { L T ^-1 }
