4. What was the largest position you reached when making your second graph? What was the distance walked when you made your second graph? How does it compare to the distance walked in the first graph? 5. The displacement, Ax, is the difference between your final position, X,, and your initial position, X,. The equation for displacement Ax is:Ax = X, - X Using this equation, find the displacement for your first graph. 6. Find the displacement for your second graph. How does it compare to the displacement of your first graph? 7. Another student repeats the experiment. They start 0.5 m from the motion sensor and walk 2.5 m away from the motion sensor and stop. What was their initial position? What was their final position? What was their distance? What was their displacement? 8. Another student repeats the experiment. They start 0.5 m from the motion sensor and walk 2.5 m away from the motion sensor, stop, then walk back 2 m toward the sensor. What was their initial position? What was their final position? What was their distance? What was their displacement? It might help to make a sketch of this position graph. B. PHET SIMULATION The initial position, initial velocity, and acceleration of the man can be set. 1. Click on the Charts tab. 2. Try several combinations of position, velocity and acceleration and see how the motion and graphs differ
