Distance-Time Graph Concepts

Anil Kumar explains how to read and describe a distance-time graph using a simple example. The video covers setting up the graph, analyzing it to answer questions about distance and time, and calculating speed. It concludes with a summary of key points and a discussion on total distance and average speed.

What is placed on the x-axis in a distance-time graph?

• Distance

• Velocity

• Time

• Speed

If a person is 5 meters away after 3 minutes, how do you find this on the graph?

• Look at the x-axis at 5 minutes

• Look at the y-axis at 3 meters

• Look at the x-axis at 3 minutes and find the corresponding y-value

• Look at the y-axis at 5 meters and find the corresponding x-value

How can you find the time when an object is a certain distance away?

• By looking at the x-axis at that distance

• By drawing a line from the distance on the y-axis to the graph and then down to the x-axis

• By looking at the y-axis at that distance

• By calculating the slope at that point

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

• By calculating the slope of the graph

• By counting the number of steps

• By measuring the distance

• By looking at the time intervals

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

• It measures the acceleration

• It shows the total distance traveled

• It represents the time taken

• It indicates the speed of the object

What does a horizontal line on a distance-time graph indicate?

• Constant speed

• Acceleration

• Rest

• Deceleration

Why is speed always positive even if the distance decreases?

• Because the graph is always positive

• Because time is always increasing

• Because distance cannot be negative

• Because speed is a scalar quantity

How do you calculate the total distance traveled from a distance-time graph?

• By multiplying the speed by time

• By adding up all the distances covered in each interval

• By subtracting the initial distance from the final distance

• By measuring the final point on the graph

What is the formula for average speed?

• Total time divided by total distance

• Total distance divided by total time

• Initial speed plus final speed divided by two

• Final speed minus initial speed

If a person returns to the starting point, what is the total distance traveled?

• Half the distance of the outward journey

• Equal to the distance of the return journey

• Zero

• Twice the distance of the outward journey
