Read the scenario.
A car travels 25 m/s forward for 10 s.
Which option accurately identifies the measurements within the scenario that are vector quantities and describes why?
Responses
The measurement 25 m/s is the only vector quantity because it is a measurement of speed.
The measurement 25 m/s is the only vector quantity because it is a measurement of speed.
The measurement 10 s is the only vector quantity because it measures time.
The measurement 10 s is the only vector quantity because it measures time.
The measurement 25 m/s forward is the only vector quantity because it is a measurement that includes a direction.
The measurement 25 m/s forward is the only vector quantity because it is a measurement that includes a direction.
The measurements 25 m/s and 10 s are vector quantities because these numbers are both measurements that do not include direction.
The correct response is:
The measurement 25 m/s forward is the only vector quantity because it is a measurement that includes a direction.
Explanation: A vector quantity is a measurement that has both magnitude and direction. In this scenario, the measurement "25 m/s forward" includes a direction (forward), making it a vector quantity. On the other hand, the measurement "10 s" only has magnitude (time) and does not include a direction, so it is not a vector quantity.
The correct option is:
The measurement 25 m/s forward is the only vector quantity because it is a measurement that includes a direction.
In this scenario, the measurement of 25 m/s is a vector quantity because it includes both a magnitude (25 m/s) and a direction (forward). This makes it a vector quantity. On the other hand, the measurement of 10 s is a scalar quantity because it only has a magnitude (10 s) and does not include a direction.
