2.1 Position, Velocity, and Speed

The displacement ∆x of a particle is defined asits change in position in some time interval. As the particle moves from an initial position xi to a final position xf , its displacement is given by

∆x= xf - xi

Example 2.1 Calculating the Average Velocity and SpeedFind the displacement, average velocity, and average speed of the car in Figure 2.1 between positions A and F.
