Distance-time graphs

Front

What is a distance-time graph?

Back

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

Front

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

Back

The slope of a distance-time graph represents the speed of the object. A steeper slope indicates a higher speed.

Front

How do you calculate distance using speed and time?

Back

Distance = Speed × Time. For example, if a person jogs at 12 km/hr for 2 hours, the distance is 12 km/hr × 2 hr = 24 km.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, usually expressed in units like km/hr or m/s.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

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

Back

A horizontal line indicates that the object is at rest; it is not changing its position over time.

Front

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

Back

A straight diagonal line indicates that the object is moving at a constant speed.

Front

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

Back

A curved line indicates that the object is accelerating or decelerating; its speed is changing.

Front

How can you determine the total distance traveled from a distance-time graph?

Back

You can determine the total distance traveled by looking at the vertical distance on the graph at the end of the time interval.
