The study of motion, without regard to any underlying causes, is called ___________________.Motion can be defined by certain physical quantities such as speed, distance, time, velocity, acceleration etc.These quantities are divided into two general types:_______________are quantities that are specified by both magnitude and direction_______________are quantities that are specified by a value (magnitude) only and no direction.DistanceMeasure of total travel regardless of directionScalar or Vector?DisplacementNet travel of an object measured from its starting point to its end pointRequires directionScalar or Vector?PositionThe displacement from a given originScalar or Vector?Symbol:12706351143000Example 1 1866900167640How to add vectors:Example 2Trevor rides his bike every day from his home to school in a time of 0.5 hours (30 minutes).
