2. Active Figure 4.7  The parabolic path of a projectile that leaves the origin with a velocity vi. The velocity vector v changes with time in both magnitude and direction. This change is the result of acceleration in the negative y direction. The x component of velocity remains constant in time because there is no acceleration along the horizontal direction. The y component of velocity is zero at the peak of the path.
At the Active Figures link at you can change launch angle and initial speed. You can also observe the changing components of velocity along the trajectory of the projectile.

5. Figure (b) Schematic diagram of the projectile-target demonstration. Both projectile and target have fallen through the same vertical distance at time t, because both experience the same acceleration ay = –g.

7. Figure 4.1  A particle moving in the xy plane is located with the position vector r drawn from the origin to the particle. The displacement of the particle as it moves from A to B in the time interval ∆t = tf – ti is equal to the vector ∆r = rf – ri.
Fig. 4.1, p.78

8. Figure 4.3  As a particle moves between two points, its average velocity is in the direction of the displacement vector ∆r. As the end point of the path is moved from B to B’ to B’’, the respective displacements and corresponding time intervals become smaller and smaller. In the limit that the end point approaches A, ∆t approaches zero, and the direction of ∆r approaches that of the line tangent to the curve at A. By definition, the instantaneous velocity at A is directed along this tangent line.

14. Figure 4.19   (b) The total acceleration a of a particle moving along a curved path (which at any instant is part of a circle of radius r) is the sum of radial and tangential components. The radial component is directed toward the center of curvature. If the tangential component of acceleration becomes zero, the particle follows uniform circular motion.
