Exploring Speed Graphs: Distance vs Time Analysis

This video tutorial explains speed graphs, focusing on how distance and time are represented. It uses a turtle's journey to illustrate concepts like movement, pauses, and changes in direction. The video also covers how to interpret line slopes on graphs, calculate average speed, and understand acceleration. Key formulas and examples are provided to aid comprehension.

What two variables are used in a speed graph?

• Speed and Distance

• Time and Acceleration

• Distance and Time

• Speed and Time

If a turtle moves 10 meters in 10 minutes, what is its speed?

• 10 m/min

• 0.5 m/min

• 2 m/min

• 1 m/min

What does a flat line on a speed graph indicate?

• The object is moving forward

• The object is accelerating

• The object is moving backwards

• The object is not moving

What does a downward sloping line on a speed graph represent?

• The object is moving forward

• The object is moving backwards

• The object is accelerating

• The object is decelerating

How do you calculate the change in distance?

• Multiply the initial and final positions

• Subtract the initial position from the final position

• Add the initial and final positions

• Divide the final position by the initial position

What does a steeper line on a speed graph indicate?

• The object is moving backwards

• The object is moving slower

• The object is not moving

• The object is moving faster

What is acceleration?

• Constant speed

• A flat line on a graph

• A change in speed or direction

• Moving backwards

Where on the graph does the turtle experience acceleration?

• Where the line is flat

• Where the line is steepest

• Where the line is straight

• Where the line changes slope

How do you calculate average speed?

• Total distance divided by total time

• Total time divided by total distance

• Initial speed plus final speed

• Initial distance minus final distance

What is the average speed of the turtle from time 10 to time 30?

• 1.25 m/min

• 0.75 m/min

• 1.5 m/min

• 0.5 m/min
