Displacement
position = position
final

initial
Vector (magnitude and direction)
net
distance traveled, regardless of path taken
units = meters
average velocity
= displacement/time
v =
x/
t
v = d/
t
Vector (magnitude and direction)
units = m/s
Speed
Total distance traveled/time
Scalar (magnitude only)
Can never be negative
units - m/s

acceleration
change in velocity/time
a =
v/
t
object can accelerate even if speed is constant
Vector (magnitude and direction)
units = m/s

slope of a x vs t graph
gives velocity
slope of a v vs t graph
gives acceleration
area under v vs t graph
gives displacement
