Distance Time Graphs (Do Now)

Front

What does a distance-time graph show?

Back

A distance-time graph shows how the distance traveled by 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.

Front

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

Back

A straight diagonal line represents constant speed.

Front

What does a curve that slopes upwards on a distance-time graph indicate?

Back

A curve that slopes upwards indicates acceleration (speeding up).

Front

What does a curve that slopes downwards on a distance-time graph indicate?

Back

A curve that slopes downwards indicates deceleration (slowing down).

Front

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

Back

Speed can be determined by calculating the slope of the line on the graph.

Front

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

Back

The steepness of the line represents the speed; a steeper line indicates a faster speed.

Front

If an object returns to its starting point, what does the distance-time graph look like?

Back

The graph will return to the horizontal axis, indicating zero distance from the starting point.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a person travels 10 meters in 5 seconds, what is their speed?

Back

Speed = 10 m / 5 s = 2 m/s.
