Vectors have size and ___
Scalars have only ____

Answer 1

direction

size

Step-by-step explanation:

Vectors are physical quantities with both magnitude or size and direction.

Scalars are physical quantities with only size but not direction.

• Examples of vectors are velocity, displacement and force.
• Examples of scalar are distance and speed

When describing a vector, on must specify its magnitude and direction.

Only the size of scalar quantities are needed to describe them.
