Question

unit test google classroom microsoft teams select the correct options in the table. quantity includes direction? scalar or vector? speed yes scalar velocity no vector

Explanation:

Step1: Recall scalar - vector definitions

Scalars have only magnitude, vectors have magnitude and direction.

Step2: Analyze speed

Speed is the rate of change of distance. It has only magnitude (e.g., 50 km/h), no direction. So, for speed, "Includes direction?" is no, and it is a scalar.

Step3: Analyze velocity

Velocity is the rate of change of displacement. Displacement has both magnitude and direction, so velocity has magnitude and direction. So, for velocity, "Includes direction?" is yes, and it is a vector.

Answer:

speed: no, scalar
velocity: yes, vector
