A car travels 100 km. The highest speed of the car is 90 km/h and the lowest speed is 30 km/h. The journey takes two hours. What is the average speed for the journey?

The diagram shows the speed/time graph for an object moving at constant speed.

What is the distance travelled by the object in the first 3 s ?

A car accelerates from traffic lights. The graph shows the car’s speed plotted against time. How far does the car travel before it reaches a constant speed ?

Four students try to explain what is meant by acceleration. Which student makes a correct statement ?

A car travels at various speeds during a short journey. The table shows the distances travelled and the time taken during each of four stages P,Q,R and S.

During which two stages is the car travelling at the same speed?

Five telegraph poles are positioned at equal distances along the side of a road. A car accelerates until it is level with pole 4. The car then continues along the road at a steady speed. The times taken to travel between one pole and the next are measured. Which time is the greatest ? The time between
