velocity-time graphs

1) What is the meaning of slope on a v-t
graph?
2) How would you find displacement on a
v-t graph?
3) How can you tell when the object on the
graph is moving forward?
4) How can you tell when the object is not
moving?
5) How can you tell when the object is
speeding up? Slowing down?
6) What
was the acceleration from time t = 4
s to t = 8 s?
7) What
was the acceleration from time t = 0
s to t = 8 s?
8) What was the average acceleration for
the entire trip?
9) What
was the instantaneous velocity at 6 s?
10) What was the average velocity between t = 0 s and t = 4 s?
11) What
was the object’s displacement from time t
= 0 s to t = 2 s?
12) What was the object’s displacement from
time t = 4 s to t = 10 s?
13) What
was the average velocity between t = 4
s and t = 10 s? (Be careful with this
one. Remember, velocity equals displacement’s
rate of change.)
14) What
was the average velocity over the entire
graph?
15) What
was the average speed over the entire
graph? (It’s another tricky one. Remember, velocity involves displacement, but
speed involves distance.)
16) Between
which times is the car moving forwards?
17) When is
the car not moving?
