Distance-Time Graphs

Front

What two measurements are necessary for calculating speed?

Back

Distance and time

Front

What does a distance-time graph with a straight line represent?

Back

Constant Speed

Front

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

Back

Stationary (not moving)

Front

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

Back

High speed

Front

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

Back

Low speed

Front

What does a curve on a distance-time graph represent?

Back

Acceleration or deceleration

Front

If a distance-time graph shows a line going upwards, what does it indicate?

Back

The object is moving away from the starting point.

Front

If a distance-time graph shows a line going downwards, what does it indicate?

Back

The object is returning to the starting point.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What does it mean if the distance-time graph is a vertical line?

Back

It is impossible; it indicates infinite speed.
