Vectors vs. Scalars
►Quantities
can be divided into two
categories - vectors and scalars.
►A vector quantity is a quantity which is
fully described by both magnitude and
direction.
►A scalar quantity is a quantity which is
fully described by its magnitude.
Examples of vector quantities
include:
displacement
► velocity
► acceleration
► and force.
►
the quantity demands both a
magnitude and a direction
►For
example,
suppose that your
teacher tells you that
"a bag of gold is
located outside the
classroom; to find it,
displace yourself 20
meters."
Arrows
► Vector
diagrams depict a vector by use of
an arrow drawn to scale in a specific
direction.
Positive & Negative
► Vectors
positive
► Vectors
going right (east) or up (north) are
going left (west) or down (south)
are negative
Vector Addition
► Two
vectors can be added together
