Distance-Time Graphs Flashcards

All 4 cards in this deck

What does the gradient of a distance–time graph represent?

The speed of the object.

What does a horizontal line on a distance–time graph show?

The object is stationary (not moving).

True or false? A straight sloping line on a distance–time graph shows an object that is accelerating.

False. A straight sloping line shows constant speed; a curved line shows changing speed.

How do you find the speed at one particular time from a curved distance–time graph?

Draw a straight line that just touches the curve at that time (a tangent); the speed equals the gradient of that line.
