distance time graphs

Question 1

What does a distance-time graph show?

Answer 1

A distance-time graph shows how the distance of an object moving in a straight line varies over time.

Question 2

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

Answer 2

A straight line represents constant speed.

Question 3

What does the slope of the straight line indicate on a distance-time graph?

Answer 3

The slope of the straight line represents the magnitude of the speed.

Question 4

What does a very steep slope mean on a distance-time graph?

Answer 4

A very steep slope means the object is moving at a large speed.

Question 5

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

Answer 5

A shallow slope means the object is moving at a small speed.

Question 6

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

Answer 6

A flat, horizontal line means the object is stationary (not moving).

Question 7

How is changing speed represented on a distance-time graph?

Answer 7

Changing speed is represented by a curve.

Question 8

What does an increasing slope indicate on a distance-time graph?

Answer 8

If the slope is increasing, the speed is increasing (accelerating).

Question 9

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

Answer 9

If the slope is decreasing, the speed is decreasing (decelerating).

Question 10

How can speed be calculated from a distance-time graph?

Answer 10

The speed of a moving object can be calculated from the gradient of the line on a distance-time graph.
