Use mathematical and computational thinking to apply formulas related to an object’s displacement, constant velocity, average velocity and constant acceleration. Interpret the meaning of the sign of displacement, velocity, and acceleration.
Construct explanations for what is meant by “constant” velocity and “constant” acceleration (including writing descriptions of the object’s motion and calculating the sign and magnitude of the slope of the line on a position-time and velocity-time graph).
Develop and use models to represent an object’s displacement, velocity, and acceleration (including vector diagrams, data tables, motion graphs, dot motion diagrams, and mathematical formulas).
Plan and conduct controlled scientific investigations on the straight-line motion of an object to include an interpretation of the object’s displacement, time of motion, constant velocity, average velocity, and constant acceleration.
Obtain information to communicate the similarities and differences between distance and displacement; speed and velocity; constant velocity and instantaneous velocity; constant velocity and average velocity; and velocity and acceleration.
