Interpreting Distance-Time Graphs

The video tutorial explains how to interpret distance-time graphs by examining the steepness of lines. It covers three examples: constant speed, varying directions, and acceleration/deceleration. Key concepts include understanding how steepness relates to speed and how curved lines indicate changes in speed.

What does a line with no steepness on a distance-time graph indicate?

• Decreasing speed

• Increasing speed

• No speed

• Constant speed

If a line on a distance-time graph has some steepness, what does it indicate about the object's speed?

• The object is slowing down

• The object is moving at a constant speed

• The object is not moving

• The object is speeding up

In the first example, what is the direction of the object when it has constant speed?

• No direction

• Towards home

• Changing direction

• Away from home

In the second example, what does it mean if the line has no steepness?

• The object is moving away from home

• The object is changing direction

• The object is moving towards home

• The object is not moving

In the second example, what is the direction of the object when it is moving with some steepness?

• Towards home

• Changing direction

• Away from home

• No direction

In the third example, what does a curved line on a distance-time graph indicate?

• Changing direction

• Changing speed

• No speed

• Constant speed

What does it mean if the steepness of a curved line on a distance-time graph increases?

• The object is slowing down

• The object is speeding up

• The object is not moving

• The object is moving at a constant speed

What does it mean if the steepness of a curved line on a distance-time graph decreases?

• The object is not moving

• The object is slowing down

• The object is speeding up

• The object is moving at a constant speed

In the third example, what is the direction of the object when it is speeding up?

• Changing direction

• Towards home

• Away from home

• No direction

In the third example, what is the direction of the object when it is slowing down?
