Question

1. what goes on the x - axis on a speed - distance graph? what goes on the y - axis?

x - axis: ________________________ y - axis: ________________________

1. fill out the chart based on the correct units for each scenario. place a check if the example would be used to describe time, distance, or average speed.

unit example	time	distance	average speed	did not fit into any of the other categories
meters/minutes
kilometers
grams
hours
miles
miles/hour
kilometers/hour
newtons

1. describe what is happening on the graph below:

Explanation:

Step1: Answer graph axis question

For a speed-distance graph, the independent variable (distance) is on the x-axis, and the dependent variable (speed) is on the y-axis.

Step2: Categorize units for the chart

Match each unit to time, distance, speed, or the "did not fit" category using unit definitions:

• Time: units measure duration
• Distance: units measure length
• Average Speed: units are distance/time
• Did not fit: units for mass/force

Step3: Analyze distance-time graph segments

Interpret each segment by slope (slope = speed):

• Segment A: Positive slope = constant speed
• Segment B: Zero slope = no movement
• Segment C: Positive slope = constant speed
• Segment D: Negative slope = constant return speed

Answer:

X-axis: Distance
y-axis: Speed

Question 21

• Segment A (0-3 seconds): The object travels at a constant speed, moving 6 meters away from the starting point.
• Segment B (3-6 seconds): The object is stationary; its distance from the start does not change.
• Segment C (6-8 seconds): The object resumes moving at a constant, slower speed than segment A, traveling an additional 2 meters.
• Segment D (8-10 seconds): The object travels back to the starting point at a constant speed, covering 8 meters in 2 seconds.
