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.

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

Motion with constant acceleration
as a ball falls from the ceiling its displacement changes as well as velocity. figure 2-11 pg.51
