You have learned of two fundamental units that are not vector quantities. Which are they?

mass

time

velocity

gravity

acceleration

Mass and time are not vector quantities.

Explanation:

All the physical quantities can be classified into two major categories that is:

Scalar Vector

Scalar quantities

They are those that describes only the magnitude and they are regarded as incomplete quantities as they don't provide complete information.

For example : Speed, Mass, Time etc

Vector quantities

They are complete quantities that can be described in magnitude as well as direction.

For example : Velocity, gravity, Acceleration etc
