Distance time graphs

Front

What is speed?

Back

A measurement of how fast an object is moving.

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

What does a distance-time graph represent?

Back

It shows how the distance of an object changes over time.

Front

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

Back

The object is at rest; it is not moving.

Front

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

Back

The object is moving quickly.

Front

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

Back

The object is moving slowly.

Front

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

Back

The object is returning to the starting point.

Front

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

Back

By calculating the slope of the line on the graph.

Front

What is the formula for speed?

Back

Speed = Distance / Time.

Front

What unit is speed commonly measured in?

Back

Meters per second (m/s).
