Applying Kinematic Equations to Situations of Constant Acceleration Note that any motion starting or ending in a motionless state will simplify the equations. Go through the algebra to show how the kinematic equations can be simplified when some of the values are zero. Refer to the graph of 2 d vs t 2 and explain why this is a straight line, whereas d vs t would be nonlinear. Ask students why all three of the plots are straight lines. Give examples of increasing, decreasing, and constant acceleration, and explain how each affects the shape of plots of velocity versus time. Explain that Figure 3.7 represents constant acceleration because it is a straight line. Use everyday examples from transportation, sports, or amusement park rides. Contrast constant velocity with changing velocity. Build on the understanding of velocity to introduce acceleration.

Show how the graph would change for both negative and positive acceleration. Explain that Figure 3.6 would show a straight line if velocity were changing that is, if the object were accelerating.

Pick a segment on the graph and explain how to find the slope at this segment. Point out that the plot starts at (0,0) because the initial velocity is zero. Relate the simplified equation v ¯ = d t v ¯ = d t to a graph of displacement versus time. Remind students that they studied velocity in earlier chapters.

Be sure everyone is completely comfortable with the idea that velocity is displacement divided by the time during which the displacement occurs. The first kinematic equation relates displacement d, average velocity v ¯ v ¯, and time t. Constant acceleration is acceleration that does not change over time. The kinematic equations that we will be using apply to conditions of constant acceleration, except where noted, and show how these concepts are related. We are only concerned with motion in one dimension. We are studying concepts related to motion: time, displacement, velocity, and especially acceleration. How the Kinematic Equations are Related to Acceleration Explain that these equations can also be represented graphically. Review graphical analysis, including axes, algebraic signs, how to designate points on a coordinate plane, i.e., ( x, y), slopes, and intercepts. Explain that this section introduces five equations that allow us to solve a wider range of problems than just finding acceleration from time and velocity. Briefly review displacement, time, velocity, and acceleration their variables, and their units. (A) generate and interpret graphs and charts describing different types of motion, including the use of real-time technology such as motion detectors or photogates.
