(19 cards)
What describes the motion of an object over time?
A journey
A journey is a term used to describe the movement of an object from one point to another over a period.
How can a journey be represented visually?
Using a distance-time graph
A distance-time graph illustrates how distance changes over time.
What does the x-axis of a distance-time graph represent?
Time in seconds
What does the y-axis of a distance-time graph represent?
Distance in metres
What is indicated by a straight diagonal line on a distance-time graph?
The object is travelling at a constant speed
What does the gradient of the line on a distance-time graph represent?
The speed of the object
At which point does the object accelerate according to the distance-time graph?
At point b
What does a curved line that gets steeper on a distance-time graph indicate?
The object is accelerating
What happens to the line at point d on a distance-time graph?
The object is decelerating
What does a flat line on a distance-time graph indicate?
The object is stationary
How is speed calculated from a distance-time graph?
By calculating the gradient of the line
What units are used for speed if distance is in metres and time is in seconds?
m/s
What units are used for speed if distance is in kilometres and time is in hours?
km/h
Fill in the blank: The gradient of the line on a distance-time graph is equal to _______.
the speed
At which point in the journey was the car stationary?
At point e
What does a steeper straight line on a distance-time graph indicate?
The object is travelling at a faster constant speed
What is the total distance travelled by the car according to the distance-time graph?
To be determined from the graph
How far did the car travel between 2 seconds and 3 seconds?
To be determined from the graph
Calculate the speed of the car between 2 seconds and 3 seconds.
To be determined from the graph
