Question

what is velocity ? Explain.​

Answer 1

Hey Friend here is your Answer

Velocity defines the direction of the movement of the body or the object. ... It can be defined as the distance covered by an object in unit time. Velocity can be defined as the displacement of the object in unit time.

Hope it helps you ✌☺️

Thank You :)

Answer 2

Answer:

Answer-

$\rightarrow$ 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 equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).

Step-by-step explanation:

$\rightarrow$ Velocity is speed with a direction, so distance over time with a specific direction.

$\rightarrow$ And acceleration, the king of them all, is distance over time squared, aka the rate at which velocity changes. Whether you are speeding up, slowing down, or changing directions, you are changing your velocity and thus, accelerating.

$\rightarrow$ Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.

$\rightarrow$ The sign of the velocity depends on the coordinate system chosen to define the position.

$\rightarrow$ A positive velocity simply means that the object is moving in the positive direction, as defined by the coordinate system, while a negative velocity means the object is traveling in the other direction.
