I think we need to introduce vector addition here also?
Maybe, a new model or applet for manipulating vectors.

<b>Why are we starting out an activity on [The Movement of
Electrons] with a discussion of vectors? You can probably appreciate
the fact that if you want to predict where someone will be after
traveling for two hours at a certain speed, you will also want to
know the direction that they are traveling. Thus, when we say that a
car is traveling at 65 mph northward, we are really talking about a
vector. That is, a vector has both magnitude (65 mph) and direction
(northward).</b>

As we see here, the length of the arrows represent how fast a car is
traveling in its lane. Cars in the left lane are traveling at the
same speed as the cars in the right lane. That is they have the same
magnitude, which we sometimes refer to as a scalar. (Scalars are
simply measurements that do not include direction, which vector
notation requires.) However, their vectors are different because
their directions are different.
<p>
</p>
<p>
So, vectors are a concise way of answering two questions: How
much? and What direction?
</p>
<p>
</p>
<p>
We say that two vectors are equal if and only if their direction <b>and</b>
magnitude are the same.
