Learning Objectives
After completing this lesson you will be able to:
 Define the following terms: average speed, average velocity, constant speed, constant velocity, instantaneous speed, and instantaneous velocity.
 Distinguish among: speed and velocity; constant, average and instantaneous speed; constant, average and instantaneous velocity.
 Calculate: constant and average speed; constant and average velocity.
 Construct a position versus time graph or a displacement versus time graph of a moving object.
 Determine the displacement of an object on a velocity versus time graph or a position versus time graph.
 Interpret position versus time graphs or displacement versus time graphs to determine type of motion and position at a specific instant.
 Analyze position versus time graphs or displacement versus time graphs to determine constant velocity, average velocity and instantaneous velocity.
 Solve problems relating to speed and velocity.
 Use charts, tables and graphs to obtain numerical information.
 Estimate the velocity of various moving objects.
 Determine the slope of a graph and derive its correct units.
