VECTORS
Scalar: a
physical quantity that has
magnitude only leg time, mass, volume
Vector: a
physical quantity that has both
magnitude and direction leg force, weight, velocity)
Vector notation:
When whole rector, add
representing ar row
pointing to
right above symbol
·
E'represents the force vector
F of force
represents only the magnitude the
·
vector
GRAPHICAL REPRESENTATION:
Drawn as ar rows
Has both
magnitude (length) and direction (direction in which it points)
Starting point tail

direction at its TAIL
Method 1: Compass directions
