Technically, the term velocity means how fast and in what direction is a given object moving; knowing the velocity is certainly part of calculating how long it takes to get from one place to another, but you also have to know how far apart those places are. If two locations are 100 miles apart, and you can drive that distance at 50 miles per hour, then the trip takes two hours.
True. Velocity is defined as the speed of an object in a given direction. If the object changes it's speed or the direction in which it is traveling, so has it's velocity changed.
The word "only" makes that statement false. Velocity does describe the direction
in which the object is moving, but it also includes the object's speed.
No. Velocity is a vector that describes both the direction in which an object is moving and its speed in that direction.
As regards a moving object, we call the measure of the speed and direction it is moving its velocity.
Velocity tells you what speed a moving object travels at and in what direction.

A vector is used to represent direction and magnitude of speed. Velocity is the speed of an object and a specification of its direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. Therefore a vector can be used to represent a velocity. The term "resultant velocity" implies a change in velocity which can be determined using vector analysis.
A vector
The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.
Velocity only describes the speed. Vector describes both speed and direction. That entails trigonometry.
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
