Document Summary

*using kinematics definitions to extract useful information from graphs. *two-dimensional model -> the vector nature of the kinematic quantities is used with the kinematic equations. *displacement: the distance between the final position and initial position of an. *velocity: the displacement change as a function of time. *position : the places that an object is respect to origin. object, nothing about how we get there. *acceleration: the motion change as a function of time, how fast velocity change. Step 1: clarify the start point -> reference point. Step 2: highly recommended to draw a graph/diagram to show how the object moves -> direction and distance. Example: objects a moves round a square with length of 10cm for one and half loops, showing as the picture. However, for displacement, we just compare the distance between point a and point f, which is 10cm. *motion diagram -> show an object that is mowing between successive positions with equal time intervals.
