Step one.     Reset all of the "moving mans" to zero.  Step Two.    Use the position slider to move the man near the tree (-10.0 m) Step Three. Give him a velocity of 1.2 m/s and an acceleration of 0 m/s/s  Step Four.    Start the man in motion until he hits the wall, then stop recording.

Looking at the value for the velocities in both "experiments" (1.2 m/s and -1.2 m/s) what effects did these values have on the behavior of the position verses time graph.
• A.

The first experiment (1.2 m/s) had a positive slope, and the second experiment (-1.2 m/s) had a negative slope.

• B.

The second experiment (1.2 m/s) had a positive slope and the first experiment (-1.2 m/s) had a negative slope.

• C.

No changes in the shape of the graphs

Looking at the value for the velocities in both "experiments" (1.2 m/s and -1.2 m/s) what effects did these values have on the behavior of the velocity verses time graph.
• A.

The first experiment (1.2 m/s) had a velocity verses time that was upper pointing / positive slope. The second experiment (-1.2 m/s) had a velocity verses time that was downward pointing / negative slope.

• B.

The second experiment (1.2 m/s) had a velocity verses time that was upper pointing / positive slope. The first experiment (-1.2 m/s) had a velocity verses time that was downward pointing / negative slope.

• C.

No changes in the shape of the graphs, but the first experiment had a constant value above zero and the second experiment was constant value below zero
