CAIE IGCSE Physics 1.2.4 Distance–time & speed–time graphs

Practise plotting, sketching and interpreting distance-time and speed-time graphs for changing motion, constant speed and stopping.

Syllabus
2026–2028
Course
Physics 0625

Exam points

  • plot speed-time or distance-time sections from stated times, speeds and distances
  • interpret graph shapes to describe acceleration, deceleration, rest and constant speed
  • use gradient or area under a motion graph to find speed, acceleration or distance

1.2.4—Distance–time and speed–time graphs question 1

[Maximum number: 3]

Fig. 1.1 is the distance-time graph for a moving car.

Fig. 1.1

Fig. 1.1

At time t=45 st=45 \mathrm{~s}, the car starts to decelerate. At time t=55 st=55 \mathrm{~s} and at a distance of 400 m from the starting point, the car stops. It then remains stationary for 5.0 s .

On Fig. 1.1, draw a possible continuation of the distance-time graph.
