Vectors simply are direction-conscious, path-independent quantities which depend solely upon the initial and final state of an object. Vectors are always expressed fully by use of a magnitude and a direction.ī. FALSE - Both scalar and vector quantities have a magnitude or value expressed with a given unit additionally, a vector quantity requires a direction in order to fully express the quantity.Ĭ. TRUE - Vectors are fully described by magnitude AND direction scalars are not described with a direction.ĭ. TRUE - Scalars such as distance would depend upon the path taken from initial to final location. If you run around the track one complete time, your distance will be different than if you take a step forward and a step backwards. The path MATTERS distance (like all scalars) depends upon it. On the other hand, the displacement (a vector quantity) is the same for both paths.Į. FALSE - Vectors are the types of quantities which depend only upon initial and final state of the object. For instance, the vector quantity displacement depends only upon the starting and final location.į. FALSE - This is certainly not a speed quantity though the unit is appropriate for speed, the statement of the direction is inconsistent with speed as a scalar quantity. FALSE (a rather picky FALSE) - If a direction was included, then this would be an acceleration value. The unit is characteristic of acceleration but the lack of direction is inconsistent with acceleration being a vector quantity. Which of the following statements about distance and/or displacement are TRUE? List all that apply.Distance is a vector quantity and displacement is a scalar quantity.
