which of the following best explains velocity? A.the speed & direction of an object in motion C.only the change of direction of an object in motion D.the direction of an object in motion
A. The speed and direction.
The correct answer that best explains velocity is option (A): the speed and direction of an object in motion.
Velocity is a vector quantity, which means it has both magnitude (the speed or rate of change of distance) and direction. In the context of physics, velocity refers to how fast an object is moving in a specific direction. So, if an object is moving with a certain speed and in a particular direction, that combination of speed and direction is what defines its velocity.
