Run the virtual lab, "the moving man." (You may have to update the version of Java.)

1. Set the acceleration to zero. Try various values and signs of position and velocity. Does a negative value of the position imply a negative velocity? Explain.

2. Fix the position at zero. Try the following 4 combination of velocity and acceleration: (+,+) (+,-),(-,+),(-,-). Describe the motion of each case. Among this, let us focus on the negative velocity and positive acceleration. Does the man move faster or slower? Is this consistent with what you expected? Explain.
