### Slide 2

Vector Addition

Suppose 3 forces act on an object

at the same time. Fnet is not 15 N

because these forces aren't

working together. But they're not

8N

completely opposing each either. 4N

So how do find Fnet ? The answer

is to add the vectors ... not their

magnitudes, but the vectors

themselves. There are two basic 3N

ways to add vectors w/ pictures:

· Tip to tail method

· Parallelogram method…read more

### Slide 3

Tip to Tail Method 20 N

12 N in-line examples

Place the tail of one vector 16 N

9N at the tip of the other. The

vector sum (also called the

resultant) is shown in red. It

starts where the black vector 20 N

16 N

21 N began and goes to the tip of

the blue one. In these 4N

9N cases, the vector sum

represents the net force.

12 N You can only add or

subtract magnitudes when

the vectors are in-line!…read more

### Slide 4

Tip to Tail 2 Vectors

To add the red and blue displacement vectors first note:

· Vectors can only be added if they are of the

same quantity--in this case, displacement. 5m

· The magnitude of the resultant must be less

than 7 m (5 + 2 = 7) and greater than 3 m

(5 - 2 = 3).

2m

Place the vectors tip to tail Interpretation: Walking 5 m in

and draw a vector from the the direction of the blue vector

tail of the first to the tip of and then 2 m in the direction

the second. of the red one is equivalent to

2m walking in the direction of the

black vector. The distance

5m walked this way is the black

r e d vector's magnitude.

### Slide 5

Commutative Property

re d+

+ r ed

blue

As with scalars quantities and ordinary numbers, the

order of addition is irrelevant with vectors. Note that

the resultant (black vector) is the same magnitude

and direction in each case.

(We'll learn how to find the resultant's magnitude soon.)…read more

### Slide 6

Tip to Tail 3 Vectors

We can add 3 or more vectors

by placing them tip to tail in

any order, so long as they are

of the same type (force,

velocity, displacement, etc.).
