Answer 5

Variable acceleration

Question 6

How is the total distance traveled found from a velocity / time graph?

Answer 6

Sum of all the areas under the graph

Question 7

How is the total displacement found on a velocity / time graph?

Answer 7

(Sum of areas above x axis) - (sum of below x axis)

Question 8

How is the area of a triangle found?

Answer 8

(Base x height) / 2

Question 9

What does ‘instantaneously at rest’ mean on a velocity / time graph?

Answer 9

The graph passes through the x axis, being stationary for a short amount of time
