Correct option is B
The correct answer is (b).
Introduction
Scalar quantities have only magnitude, no direction. Position and speed are scalars; displacement and velocity are vectors. Hence the examples are Position and Speed.
Information Booster
- Position: scalar location relative to a reference.
- Speed: rate of change of distance, scalar.
- Displacement: vector (change in position with direction).
- Velocity: vector (speed with direction).
- Option A includes velocity (vector).
- Option C includes displacement and velocity (vectors).
- Option D includes displacement and velocity.
In sports, speed (scalar) is often more commonly used than velocity for performance metrics.
