Answer:the speed at which something moves in a particular direction

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 a physical vector quantity; both magnitude and direction are needed to define it.

Other units: mph, ft/s

In SI base units: m/s

Constant

Constant velocity means that the object in motion is moving in a straight line at a constant speed. This line can be represented algebraically as: x=x0+vt x = x 0 + vt , where x0 represents the position of the object at t=0 , and the slope of the line indicates the object’s speed.

Derivative

Velocity is the derivative of position with respect to time: v(t)=ddt(x(t)). Acceleration is the derivative of velocity with respect to time: a(t)=ddt(v(t))=d2dt2(x(t)).

Directions

The direction of the velocity vector is simply the same as the direction that an object is moving. It would not matter whether the object is speeding up or slowing down. If an object is moving rightwards, then its velocity is described as being rightwards
