7.5 Vector Projection
Here you will project one vector onto another and apply this technique as it relates to force.
Projecting one vector onto another explicitly answers the question: “how much of one vector goes in the direction
of the other vector?” The dot product is useful because it produces a scalar quantity that helps to answer this
question. In this concept, you will produce an actual vector not just a scalar.
Why is vector projection useful when considering pulling a box in the direction ofvinstead of horizontally in the
direction ofu?

Consider the question from the concept.
