Significant Number Rules Significant Digits 43.74 km __________ 4302.5 g __________ Practice 0.0083 s __________ 1.200X103kg __________ Chapter 5 Forces in Equilibrium 5.1 The Force Vector 5.2 Forces and Agenda Equilibrium 5.3 Friction The Force Vector Scalars and Vectors Scalar has magnitude (size/amount) ◼A scalar is a quantity that can be completely described by a single value called its magnitude. ◼ Magnitude means the amount, and always includes units of measurement. ◼ Temperature is a good example of a scalar quantity. Vector has both magnitude and direction ◼ Sometimes a single number does not include enough information to describe a measurement. ◼A vector is a quantity that includes both magnitude and direction. ◼ Vectors are useful when giving directions.
