Question

Which of the following determine an object's velocity? A. speed and direction B. direction and acceleration C. speed and mass D. speed, direction, and acceleration

Answer 1

Velocity is a vector quantity, so it will have both speed and direction. The answer is A.

Answer 2

Answer:

The answer is A. speed and direction

Explanation:

Velocity is the physical magnitude of a vector type that relates the change of position with time, that is, it is the distance traveled by an object in the unit of time. In order to define the speed of an object, the distance traveled per unit of time must be considered, as well as the direction of the displacement, for this reason, the velocity is expressed as a vector magnitude.
