Damon Pryor Physics Notes 12/6/06 Pages 14-17 Kinematics: The classification and comparison of motion. One Dimensional Motion: Objects that move along a single axis. Three Restrictions of motion: 1.) Motion is along a straight line only, that line can be vertical, horizontal, or diagonal but must be straight. 2.) Forces cause motion. (Pushes and pulls.) 3.) The moving object is either a particle or an object that moves like a particle. Meaning that every portion moves in the same direction at the same rate. Origin: the reference point used to find/locate an objects location. Also known as a zero point. Positive Direction: the direction to the right of the origin.

Unformatted text preview: Negative Direction: the direction to the left of the origin. Displacement: The change from one position to the other. Delta x = x2 x1. Magnitude: is the absolute value of the displacement. Its the distance traveled. Average Velocity: is the displacement that occurs over a particular time interval. Vavg = delta x/ delta t = x2-x1/t2-t1. On a graph its the straight line slope, somewhat like a best fit line. Average Speed: The total distance traveled divided by the change in time. Total distance referring to the number of meters covered regardless of direction....
