Distance time graphs

Front

What is a distance-time graph?

Back

A distance-time graph is a visual representation that shows how the distance of an object changes over time.

Front

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

Back

A horizontal line indicates that the object is not moving; its distance remains constant over time.

Front

What does a straight diagonal line on a distance-time graph represent?

Back

A straight diagonal line represents constant speed; the object is moving at a steady pace.

Front

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

Back

A curved line indicates acceleration or deceleration; the object's speed is changing.

Front

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

Back

Speed can be determined by calculating the slope of the line on the graph; steeper slopes indicate higher speeds.

Front

What does a steeper slope on a distance-time graph mean?

Back

A steeper slope means the object is moving faster.

Front

What does a flat line followed by a steep line indicate on a distance-time graph?

Back

It indicates that the object was stationary for a period and then started moving quickly.

Front

What is the formula for speed?

Back

Speed = Distance / Time.

Front

If an object travels 100 meters in 20 seconds, what is its speed?

Back

Speed = 100 m / 20 s = 5 m/s.

Front

What does a line that slopes downwards on a distance-time graph represent?

Back

A downward slope indicates that the object is returning to its starting point.
