Which of the following correctly groups quantities into scalars (magnitude only) and vectors (magnitude and direction)?

Answer: C. Scalar: Mass | Vector: Weight

Answer Explanation: C. Mass is a scalar quantity because it only represents the amount of matter and has no direction. Weight is a vector quantity because it is a force directed downward toward the center of a gravitational field. Speed and distance are scalars, while displacement, velocity, force, and acceleration are vectors.
