For each of the questions, the screen will be separated into three
components:
The Graph
The graph appears with a colored curve already include. In this
particular graph, the curve in question is green. It is in the same
color as the title of the graph (Position x vs Time t.) Your goal is to
identify the parameters that will reproduce that colored curve. Note
that you will be able to read the coordinates of any point on the graph
by just positioning cursor over that point and pressing and holding the
left mouse key.
The Simulation & Parameters
The grid corresponds to the simulation area. After inputting the
appropriate parameters and pressing the SimulateIt
button, a blue disk will appear on the grid and simulate the situation
set by the selected parameters. You may get the coordinates of any point
on the grid by just positioning the cursor over that point and pressing
and holding the left mouse key.
The parameters that may change are the following:

x_{o} =
Initial Position

v_{o}
= Initial Velocity

a_{o}
= Initial Acceleration

da/dt = First
derivative of the acceleration, it is zero
when the acceleration is constant.
The Controls
To run the simulation corresponding to the parameters you have chosen
and view the corresponding graph press the SimulateIt
button. You can stop the simulation at anytime by pressing the pause
button. The step_>>
and step_<<
buttons can be used to run the simulation incrementally. You need to
press the Check Answer button to check your
results.
