Here are the notes we took in science (for the people who were absent or those who took crappy notes):
Vector
A quantity whose complete description involves magnitude and direction
Represented by an arrow drawn to scale
Examples of a vector quantity: velocity, force, acceleration
Scalar
A quantity described only by magnitude
Examples of a scalar quantity: mass, volume, speed
Working with Vectors
Vectors in the same direction → add
Vectors in the opposite direction → subtract
Nonparallel vectors → use parallelogram rule
