Document Summary

Physics 1501q - lecture 2 - 1-d kinematics 8/29/18. Key (in si units): t = time (s) x = distance (m) v = velocity (m/s) a = acceleration (m/ Kinematics: the study of motion of an object without regard to its cause. 1300m 1m has 4 s. f with an uncertainty of 1m. 72 f 1 f vs. a reference value of 72. 5 f 0. 1 f is accurate because 72. 5 0. 1 f is within the range of 71 f to 73 f. Position (x): can be uniquely marked using a 3-d coordinate system. For 1-d kinematics, it"s motion along a straight line. Velocity (v): the rate of change of position in time. Acceleration (a): the rate of change of velocity in time. *note: position, velocity, and acceleration are all vectors, meaning they have both magnitude and direction (can be positive or negative).
