Example:
a Find the position at a given time
b Calculate the displacement
c Find instantaneous velocity at a given time
d Identify regions, line segments, of constant velocity
e Identify regions, line segments, of positive velocity
f Identify regions, line segments, of negative velocity
g Identify regions, line segments, of acceleration
h Identify the units of velocity or acceleration from the graph
i Determine regions of positive or negative acceleration
j Determine regions where the acceleration is zero
4 From a velocity vs. time graph be able to answer questions about acceleration and displacement
Example:
