Distance Time Graphs

Front

What does a positive slope on a distance-time graph indicate?

Back

Constant speed (moving away from the starting point)

Front

What does a negative slope on a distance-time graph indicate?

Back

Return home (moving back towards the starting point)

Front

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

Back

Not moving (at rest)

Front

What does an upward curve on a distance-time graph indicate?

Back

Acceleration (increasing speed)

Front

What does a downward curve on a distance-time graph indicate?

Back

Deceleration (decreasing speed)

Front

How do you calculate speed from a distance-time graph?

Back

Speed = Distance / Time

Front

What is the unit of speed commonly used in distance-time graphs?

Back

Meters per second (m/s) or kilometers per hour (km/h)

Front

If a distance-time graph shows a straight line, what can you conclude about the motion?

Back

The object is moving at a constant speed.

Front

What does the steepness of the slope on a distance-time graph represent?

Back

The speed of the object; a steeper slope means a higher speed.

Front

What does it mean if the distance-time graph has a flat line for a period?

Back

The object is stationary (not moving) during that time.
