Case I:
- For the velocity vs. time curve, calculate the values
at 2, 4, and 6 seconds. Remember, these points are found by finding the
area under the curve (mathematically this is integration).
- Set up the velocity scale on the graph and plot these
points.
- Sketch in the curve connecting the points. Yes, this
is a connect the dots situations, but the connecting lines should be
concaved-upward, concaved-downward, or a straight line as is appropriate
to the situation. Sketch them as realistically as possible short of
actually deriving the equations and plotting additional data point.
- Repeat the above for the displacement vs time curve.
Case II:
- Follow the instructions 1 through 3 show in Case I
for the displacement vs. time curve of Case II.
- Follow the instructions 1 through 3 show in Case I
for the acceleration vs. time curve of Case II, except, note that the
acceleration is a derivative (slope at a point) of the velocity
function.
Case III:
- Follow the instruction 2 show in Case II for the
velocity vs. time and acceleration vs. time curves of Case III.
