distance vs. timebank words: constant, not moving,increasing, decreasing)bank words: away or towardsorangespeed:________direction:______bluespeed:______position:not moving, sitting in thepoint______redspeed:______direction:______greenspeed:______direction:________part 4: graphing motion of a battery carthe battery car does the following 4 stages ofmotion:1) leaves the origin and goes 8 meters forward in 4 sec.2) the car stops for 2 sec.3) then moves backwards 3 meters in 3 sec.4) the car then stops for 1 sec. (done!)hint:1) add up all the times to get therange to figure out the scale2) add up all the meters forward toget the range for the distance anddetermine the scale

Top Graph Analysis Steps:
Step1: Analyze Orange line
Horizontal line = constant distance.
Speed: Not moving; Direction: N/A (stationary)
Step2: Analyze Blue line
Curved line, slope decreases over time.
Speed: Decreasing; Direction: away (distance increases)
Step3: Analyze Red line
Straight, positive slope = steady speed.
Speed: Constant; Direction: away (distance increases)
Step4: Analyze Green line
Curved line, slope increases over time.
Speed: Increasing; Direction: away (distance increases)

Battery Car Graph Steps:
Step1: Calculate total time
Total time = $4 + 2 + 3 + 1 = 10$ sec
Step2: Calculate position range
Max position = 8 m; Min position = 0 m; Final position = $8 - 3 = 5$ m
Step3: Define key time-position points
- 0 sec: 0 m (start at origin)
- 4 sec: 8 m (end of forward motion)
- 6 sec: 8 m (end of 2 sec stop)
- 9 sec: 5 m (end of backward motion)
- 10 sec: 5 m (end of 1 sec stop)
Step4: Set graph scale
Time axis: 1 square = 1 sec (fits 10 sec total). Position axis: 1 square = 1 m (fits 8 m max).
Step5: Plot and connect points
Draw straight lines between consecutive points to represent each motion stage.
