In this unit you gained an understanding of displacement, velocity, and acceleration. You have compared and contrasted scalar and vector quantities and explained uniform and uniformly accelerated motion. You are now able to interpret the motion of one object relative to another using displacement and velocity vectors and can explain two-dimensional motion in a horizontal or vertical plane using vector components.
From this unit, you have identified common applications of kinematics, such as the average speed of a car trip. You used the new language you acquired as you investigated the application of kinematic principles, such as determining the appropriate length of airport runways or the timing of traffic lights.
The skills that you used in Unit A will continue to be developed in Unit B—Dynamics.
