Displacement, distance and velocity

At the end of this activity, students should be able to:
– explain how to describe the position of a body and define a frame of reference
– give definitions for: path of motion, distance, and displacement
– calculate speed and velocity, and determine the differences and similarities between the concepts
– give examples of units of velocity; note this differs form above (speed)
– describe average and instantaneous velocities and give examples of each
– graphically determine the vector of resultant velocity.
