Analyzing Speed Through Distance-Time Graphs

The video tutorial explains how to determine the speed of an object using a distance-time graph. It begins by introducing the graph's axes and comparing the speeds of walking and jogging using slope calculations. The tutorial then delves into more complex graph segments, analyzing movement and rest periods. The key takeaway is understanding how slope relates to speed and how to interpret different segments of a distance-time graph.

What does the y-axis represent in a distance-time graph?

• Speed in meters per second

• Distance in meters

• Time in seconds

• Acceleration in meters per second squared

How is the slope of a line on a distance-time graph related to speed?

• The slope is unrelated to speed.

• A steeper slope indicates slower speed.

• A steeper slope indicates faster speed.

• The slope indicates acceleration.

What is the speed of a person walking if the rise is 5 meters and the run is 10 seconds?

• 5 meters per second

• 2 meters per second

• 1 meter per second

• 0.5 meters per second

What is the speed of a person jogging if the rise is 10 meters and the run is 5 seconds?

• 2 meters per second

• 1 meter per second

• 5 meters per second

• 0.5 meters per second

What conclusion can be drawn from comparing the slopes of walking and jogging?

• Walking is faster than jogging.

• Jogging is faster than walking.

• Both have the same speed.

• Speed cannot be determined from the slope.

What does a flat segment on a distance-time graph indicate?

• No movement

• Deceleration

• Acceleration

• Constant speed

If a segment of a distance-time graph shows a constant slope, what does it indicate?

• Constant speed

• No movement

• Variable acceleration

• Changing speed

In a multi-segment graph, what does a return to the starting point indicate?

• The object is stationary.

• The object is decelerating.

• The object is accelerating.

• The object is moving at constant speed back to the start.

What is the significance of a constant slope in the final segment of a distance-time graph?

• It indicates acceleration.

• It indicates no movement.

• It indicates constant speed.

• It indicates deceleration.

How can you determine the speed from a distance-time graph?

• By measuring the distance between points on the graph.

• By calculating the slope of the line.

• By counting the number of segments.

• By observing the color of the line.
