Easy -1.8 This is a 1-mark multiple choice question requiring only recognition that straight line segments on a velocity-time graph imply constant acceleration, and that corners imply instantaneous changes in acceleration. This is basic graph interpretation with no calculation or problem-solving required—significantly easier than average A-level questions.
A car starting from rest moves forward in a straight line.
The motion of the car is modelled by the velocity–time graph below:

One of the following assumptions about the motion of the car is implied by the graph.
Identify this assumption.
[1 mark]
Tick \((\checkmark)\) one box.
The car never accelerates.
The acceleration of the car is always positive.
The acceleration of the car can change instantaneously.
The acceleration of the car is never constant.
