Question 1

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

Answer 1

Stationary

Question 2

What does a diagonal line pointing upwards show on a distance-time graph?

Answer 2

Constant speed, moving away from the start point.

Question 3

What does a curved line show on a distance-time graph?

Answer 3

Acceleration or deceleration (depending on the direction of curve).

Question 4

What does a horizontal line show on a velocity-time graph?

Answer 4

Constant speed

Question 5

What does a diagonal line pointing downwards show on a velocity-time graph?

Answer 5

Deceleration

Question 6

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

Answer 6

The area under the line - Split the area into trianges, squares and rectangles and calculate the area of each one then add them together.

Answer 9

Distractions, alcohol/drugs, tiredness, speed.

Question 10

Braking distance is affected by:

Answer 10

Road conditions, worn tyres, poor brakes, speed.
