Document Summary

Also read 1. 1,1. 2,1. 4 (material not covered in class) Next lecture: uniform and non-uniform motion, average acceleration (2. 2,2. 3) Scalar: a quantity that has magnitude but no direction. Temperature, mass, speed, time, number of students in the room, no direction. Vector: a quantity that has both magnitude and direction. In physics: the arithmetic is different when dealing with vectors compared with scalars. Displacement is a vector quantity arithmetic is not the same. Displacement: indicates the change in position from the starting point to the final point in this ex start and end at the same place therefore displacement is zero. Object goes from one point in space to another after it arrives at its destination the magnitude of its displa(cid:272)e(cid:373)e(cid:374)t is . Either smaller than or equal to the distance the object travelled. Kinematics from the greek word for motion (kinema), study of motion. 1d motion (simplest case to start)- throw a ball straight up and it falls back down, drag racing.
