Question

A quantity that specifies the speed of an object moving in a definite direction ​

Answer 1

Velocity

Velocity: Velocity is the speed of an object moving in a definite direction. Velocity is a vector quantity. It can be either positive or zero or negative

Answer 2

Explanation:

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). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.
