Guida verificata passo dopo passo1
Understand the difference between scalar and vector quantities: Scalars have only magnitude, while vectors have both magnitude and direction.
Analyze each pair given in the problem to determine if both quantities are vectors.
Mass and temperature are scalars because they have magnitude only and no direction.
Speed and distance are also scalars; speed is the magnitude of velocity, and distance is the magnitude of displacement.
Velocity and displacement are vectors because they both have magnitude and direction, making them the correct pair of vector quantities.
