Scalar and Vector Quantities.
Some of the quantities (variables)
that we have talked about
in the Forces and Motion chapter are scalars
and some are vectors.
A scalar
(pronounced scay-lar) only has magnitude
(size).
A vector has both magnitude
and direction.
Examples of scalars
are
density, displacement, energy,
length, mass,
power, speed
and temperature.
Examples of vectors
are
acceleration, force,
momentum, velocity
and weight.
