One Dimensional Motion-Instructions
 

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:

  • xo = Initial Position

  • vo = Initial Velocity

  • ao = 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.
