4

A velocity-time graph with 3 lines labelled A, B and C.

Which of these lines shows a car moving at constant velocity for 30 seconds?

A

B

C

5

What does the gradient of a velocity-time graph represent?

The speed of the object

The acceleration of the object

The distance the object has travelled

6

How would an object travelling at constant speed be represented on a distance-time graph?

As a straight rising line of constant positive gradient

As a line curving upwards of increasing gradient

As a horizontal line

7
