What is the difference between a vector and a scalar?
a
A vector is only measured in SI units, where scalars are only measured in US Customary units
b
A vector measurement contains a direction and magnitude, a scalar measurement only contains a magnitude
c
A vector measurement is required for distance, a scalar measurement is required for displacement
d
A vector is only used in measuring forces, a scalar is only used in measuring mass

The correct answer is:
b A vector measurement contains a direction and magnitude, a scalar measurement only contains a magnitude.
This accurately describes the distinction between vectors and scalars. Vectors are quantities that have both magnitude and direction (like velocity and force), while scalars are quantities that have only magnitude (like temperature and mass).
