Graphs

Question 1

Distance-time graph: What does the gradient show?

Answer 1

Gradient- the object’s speed

Question 2

Distance-time graph: What do the flat, horizontal sections show?

Answer 2

Horizontal line- the object is stationary

Question 3

Distance-time graph: What do straight lines show?

Answer 3

Straight line- the object is going at a steady speed

Question 4

Distance-time graph: What do steepening and levelling curves show?

Answer 4

Steepening- the object is accelerating

Levelling- the object is decelerating

Question 5

Velocity-time graphs: What does the gradient show?

Answer 5

Gradient- acceleration

Question 6

Velocity-time graphs: What do flat sections show?

Answer 6

Flat sections- steady speed

Question 7

Velocity-time graphs: What do uphill and downhill lines show?

Answer 7

Uphill- accelerating

Downhill- decelerating

Question 8

Velocity-time graphs: What do curves show?

Answer 8

Curve- changing rate of acceleration

Question 9

Velocity-time graphs: How do you work out distance travelled?

Answer 9

Work out the area under the graph

Question 10

What is acceleration?

Answer 10

The rate of change of velocity
