Graphical Methods of Vector Addition Quiz
1. What is the defining difference between a scalar and a vector quantity?
2. When graphically representing a vector, what does the length of the arrow represent?
3. When performing one-dimensional graphical vector addition on two vectors, what is the
proper starting position for each of the two arrows representing the two forces being
combined?
a) Both arrows should start at the origin, zero on the number line, and point in the
same direction.
b) Both arrows should start at the point on the number line equal to their magnitudes,
and point in opposite directions.
c) One arrow should start at zero on the number line, pointing to the right if positive
and left if negative. The other arrow should start at zero on the number line and
point in the opposite direction.
d) One arrow should start at zero on the number line, pointing to the right if positive
and left if negative. The other arrow should start at the end of the first arrow and
point to the right if positive and left if negative.
4. Can one-dimensional vector addition be performed on more than two vectors? How or
why not?
5. True or False: When graphically adding vectors in two dimensions, each vector arrow
begins at the origin and proceeds in the direction of the vector for a distance proportional
to the magnitude of the vector.
