HOMEWORK FOR LAB 1:INTRODUCTION TO MOTION

Answer the following questions in the spaces provided.

POSITION—TIME GRAPHS

1. What do you do to create a horizontalline on a position — time graph?

n/\drw^*u U*J

2. How do you walk to create a straightline that slopes up?

3. How do you walk to create a straightline that slopes down?

U^ /,*„*£<ff s—JXVT^UYXX A^^a^u

4. How do you move so the graph goesup steeply at first, and then continues upless steeply?

5. 4iow do you walk to create a U-shapedgraph?

_Analysis:

1. Explain the significance of the slope of a distance vs. time graph. Include a discussion of positiveand negative slope.

2. What type of ^notion is occurring when the slope of a distance vs. time graph is zero?

3. What type of motion is occurring when the slope of a distance vs. time graph is constant?

4. What type of motion is occurring when the slope of a distance vs. time graph is changing?

^

5. Accelerationj^j^sjste of change of speed. When speed is constant acceleration is zero (nochange means the rate of change is zero). How does the slope of a distance vs. time graph changewhen there is acceleration?

6. Describe how a person would have tomove to create a distance vs. timegraph as pictured.
