Question

Define Velocity....

Give Some Thanks for my answers...​

Answer 1

Answer:

Velocity is the speed of an object moving in a definite direction. The SI unit of velocity is also metre per second. Velocity is a vector quantity; it has both magnitude and direction.

Explanation:

Velocity is a measure of how fast something moves in a particular direction. To define it needs both magnitude and direction. If an object moves east at 9 metres per second (9m/s), then its velocity is 9 m/s to the east. ... Speed is one part of velocity, direction is the other part.

Answer 2

${\tt{\red{\underline{\underline{\huge{AnswEr}}}}}}$

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is a physical vector quantity; both magnitude and direction are needed to define it.
