1.

TRUE or FALSE:

A vector quantity always has a direction associated with it.

a)

TRUE

b)

FALSE

2.

TRUE or FALSE:

A scalar quantity can have a direction associated with it.

a)

TRUE

b)

FALSE

3.

TRUE or FALSE:

Vectors can be added together; scalar quantities cannot.

a)

TRUE

b)

FALSE

4.

TRUE or FALSE:

Vectors can be represented by an arrow on a scaled diagram; the length of the arrow represents the vector's magnitude and the direction it points represents the vector's direction.

a)

TRUE

b)

FALSE

5.

TRUE or FALSE:

Vectors A, B, and C are added together as A + B + C. If the order in which they are added is changed to C + B + A, then the result would be different.

a)

TRUE

b)

FALSE

6.

TRUE or FALSE:

Vectors A, B, and C are added together as A + B + C. If the order in which they are added is reversed to C + B + A, then the result would be a vector with the same magnitude but the opposite direction.

a)

TRUE

b)

FALSE

7.

TRUE or FALSE:

When constructing a vector diagram for A + B + C, it is not absolutely necessary that vectors B and C use the same scale that is used by vector A.

a)

TRUE

b)

FALSE

8.

TRUE or FALSE:

The resultant in a vector addition diagram always extends from the head of the last vector to the tail of the first vector.

a)

TRUE

b)

FALSE

9.

TRUE or FALSE:

If vectors A and B are added at right angles to each other, then one can be sure that the resultant will have a magnitude that is greater than the magnitudes of either one of the individual vectors A and B.

a)

TRUE

b)

FALSE

10.

TRUE or FALSE:

If vectors A and B are added at right angles to each other, then one can be sure that the resultant will have a magnitude that is less than the arithmetic sum of the magnitudes of A and B.

a)

TRUE

b)

FALSE

11.

TRUE or FALSE:

Vector addition diagrams cannot be used to determine the resultant when there is a vector subtraction operation.

a)

TRUE

b)

FALSE
