Graphs (T1)

Question 1

The vertical axis is the …..

Answer 1

y axis

Question 2

The horizontal axis is the …..

Answer 2

x axis

Question 3

On a distance-time graph what does the line sloping down to the right mean?

Answer 3

The object is retracing its path back to the start and the distance that the object is from the start is descreasing

Question 4

How do you calculate the gradient/acceleration from the line on a velocity-time graph?

Answer 4

• make two points on each axis, as far up and down the line as possible
• y1, y2, x1, x2

Gradient = (y2 - y1) - (x2 - x1)

Question 5

What does the gradient of a velocity-time graph give us?

Answer 5

Acceleration

Question 6

How do you calculate the distance travelled from the area underneath a velocity-time graph?

Answer 6

1) calculate the area of the rectangle / square

Base x height

2) calculate the area of the triangle

1/2 x Base x Height

3) calculate the area of one graphical square
4) multiply the value of one graphical square by the total number of squares
