TACTICS BOX 4.1: Finding the acceleration vector. To find the acceleration between velocity Vi and velocity of, (Figure 1) follow these steps: V₁ 1. Draw the velocity vectors V; and of with their tails together. 15 15 15 vi Δυ 2. Draw the vector from the tip of vi to the tip of Vf. This is Av because of = √¡ + Av. 3. Return to the original motion diagram. Draw a vector at the middle dot in the direction of Av; label it a. This is the average acceleration at the midpoint between vi and Vf. Below is a motion diagram for an object that moves along a curved path. The dots are separated by equal intervals and represent the position of the object at three subsequent instants. The vectors 1 and 2 show the average velocity of the object for the first and second time intervals. Draw the vector -₁ and the acceleration vector a representing the change in average velocity of the object during the total time interval. Part A Learning Goal: Suppose an object has an initial velocity V; at time t; and later, at time tf, has velocity of. The fact that the velocity changes tells us that the object undergoes an acceleration during the time interval At = tf - ti. From the definition of acceleration, = Vf-Vi tf-ti = Δυ At ' we see that the acceleration vector points in the same direction as the vector Av. This vector is the change in the velocity Av = vf - v₁, so to know which way the acceleration vector points, we have to perform the vector subtraction of - vi. This Tactics Box shows how to use vector subtraction to find the acceleration vector.
