:
POSITION VS TIME GRAPH
Value
<->
position
Slope
<->
velocity (steeper <
-
> faster)
Sloping up (such as / )
<->
velocity positive, moving in positive direction
Sloping down (such as \ )
<->
velocity negative, moving in negative direction
Horizontal
<->
stopped (maybe just for an instant)
Curvature
<->
acceleration
Upward curvature ( such as
or
)
<->
positive acceleration (slowing down in the negative direction or speeding up in the positive direction, respectively)
Downward curvature ( such as
or
)
<->
negative acceleration (slowing down in the positive direction or speeding up in the negative direction, respectively)
Straight (such as / \ or
