Question

question 4
which of the following is not a scalar quantity?
speed
acceleration
direction
distance

Explanation:

Scalar quantities have only magnitude. Speed is the rate of motion (magnitude of motion), distance is the total path length (magnitude), and they are scalars. Direction is not a quantity in the sense of scalar - it is a property for vectors. Acceleration is a vector as it has both magnitude (rate of change of velocity) and direction (the direction of the change in velocity).

Answer:

B. Acceleration, C. Direction
