<title> Chapter 2 Help GO1DE </title> <body> <P> <h1> chapter 2</h1> <P><center> displacement change in position to final position velocity change of displacement divided by time speed is change of distance/ speed slope of velocity graph is x/t lines going up in a straight line have constant positive velocity straight line has zero velocity line going straight down negatively velocity Instananeous velocity velocity at an instant of time like whats teh velocity at: t=3.0s? this is usually compared with other graphs. </p> <br> <p> Section 2.2 Acceleration rate of change in velocity Aavg=vf-vi/tf-ti example 2b on pg 49 <br> </p> <p> acceleration has direction negative positive like east west north or going fast or slow Table of velocity and acceleration <hr> <br> <p> <table border ="1"> <tr> <td> Vi </td> <td> A </td> <td> Motion </td> </tr> <tr> <td> + </td> <td> + </td> <td> speeding up </td> </tr> </table> </br> </P> <h1> Get the picture?</h1> - and - speed up + - slow 0 0 resting <p> Motion with constant acceleration as a ball falls from the ceiling its displacement changes as well as velocity. figure 2-11 pg.51 this is the world of Chpater 2 PhysiksaAA
