Distance-Time Graph Analysis

The video tutorial by Kumar explains how to read, describe, and sketch distance-time graphs. It covers the basics of plotting graphs, understanding different types of lines and curves, and how to interpret them in terms of speed. The tutorial also includes an example scenario to illustrate how to sketch a graph based on a given situation.

What is typically plotted on the x-axis of a distance-time graph?

• Time

• Distance

• Acceleration

• Speed

Which type of line on a distance-time graph indicates an object is at rest?

• Falling line

• Horizontal line

• Curved line

• Rising line

What does a constant slope on a distance-time graph represent?

• Changing speed

• Constant speed

• Acceleration

• Deceleration

What does a horizontal line on a distance-time graph signify about the object's motion?

• The object is moving at constant speed

• The object is at rest

• The object is decelerating

• The object is accelerating

What does a rising straight line on a distance-time graph indicate?

• The object is decelerating

• The object is moving away at constant speed

• The object is moving towards at constant speed

• The object is accelerating

What does a falling straight line on a distance-time graph indicate?

• The object is decelerating

• The object is accelerating

• The object is moving towards at constant speed

• The object is moving away at constant speed

How is increasing speed represented on a distance-time graph?

• Concave up curve

• Vertical line

• Concave down curve

• Horizontal line

What does a concave down curve indicate about an object's speed?

• At rest

• Constant speed

• Speeding up

• Slowing down

In the given scenario, what does the steep slope on the return journey indicate?

• Standing still

• Running fast

• Walking backward

• Slow walking

In the practical example, what does the horizontal section of the graph represent?

• Anna is walking

• Anna is running

• Anna is standing still

• Anna is accelerating
