1.1 - Distance-time graphs Flashcards
What can we use graphs to describe?
The motion of an object
What does a distance-time graph show?
The distance of an object from a starting point against time taken
What is on the x-axis of a distance-time graph?
Time taken
What is on the y-axis of a distance-time graph?
The distance of an object from a starting point
What is the speed of an object?
The distance travelled each second
What does the gradient of a distance-time graph show?
The speed of an object
How can we show the speed of an object is becoming faster on a distance-time graph?
By making the gradient steeper
What is happening to an object when the gradient on a distance-time graph becomes less steep?
Its speed is decreasing
How can we tell if an object is stationary on a distance-time graph?
The line is horizontal
If the line is horizontal on a distance-time graph, what is happening to the object?
It is stationary
How can we tell if an object is moving at a steady speed on a distance-time graph?
The line is straight and slopes upward
On a distance time graph, if the line is straight and slopes upward, what is happening to the object?
It is moving at a steady speed
What is the equation for speed?
s=d/t
