Figure 4.6 (a) The parallel component is associated with a change of speed. Instantaneous velocity The instantaneous acceleration a. (b) 2, Instantaneous acceleration The perpendicular component is associated with a change of direction. a, Instantaneous velocity -x Instantaneous acceleration The x- and y-components are mathematically more convenient. Figure 4.6a and Figure 4.6b in your textbook each show an acceleration vector. Which of the following statements are correct? Select all that apply. The acceleration vector in the figure labeled (b) has a larger vertical component. The two accelerations are the same because they have equal magnitudes and equal directions. The two accelerations are the same but have been decomposed into components in two different ways. The acceleration in the figure labeled (a) will cause uniform circular motion because it has a component pointing toward the center of the cir
