• 36

• 49

• 7

• 6

What is a vector quantity?

• A quantity that has magnitude and direction

• A quantity with direction but no magnitude

• A quantity with direction

• A quantity with magnitude but no direction

A scalar quantity is a quantity with magnitude but no direction.

• TRUE

• FALSE

What are zero vectors?

• Vectors that consist of zero magnitude and the direction cannot be determined

• Vectors that consist of magnitude and the direction can be determined.

Two vectors are the same if both vectors consist of same magnitude and direction.
