Vectors

Which of the following could be used to define magnitude?

• Magnitude could be the value of a given quantity (e.g. 6 meters is a magnitude)

• Magnitude could be the length of a given vector (e.g. 6 units in length)

• Magnitude is the size of a given quantity (e.g. 6 miles per hour)

• All of these could define magnitude.

• scalar

• vector
