Forces
07.1 · 3 marks Distance from a Velocity–Time Graph Determine the distance travelled by the train in the first 600 s of the journey. 07.2 · 3 marks Graph Gradient, Deceleration and Braking Force Explain what happens to the braking force as the train decelerates. Use information from Figure 12. 07.4 · 6 marks Braking Distance from Force and Mass Another train travels at a speed of 60 m/s. A constant braking force of 270 000 N causes the train to decelerate and stop. mass... 07.5 · 3 marks Alcohol, Reaction Time and Stopping Distance It is illegal for train drivers to drink alcohol before driving a train. Explain how drinking alcohol would affect the stopping... 05.5 · 2 marks Resultant Force on a Raised Runway The runway was then raised at one end. The force acting through the string remained the same. Figure 11 shows this. Explain how...

Energy
01.1 · 1 mark Renewable energy resource Which of the following is also a renewable energy resource? Tick (✓) one box. 06.3 · 1 mark Air energy and temperature change The mass of air in the chamber is constant. What property of air allows a small change in internal energy to cause a large... 05.1 · 2 marks Viewing position and height measurement A student measured the maximum height reached by the toy. The student placed a vertical metre rule near the toy, and observed... 05.3 · 2 marks Toy and surroundings as an energy system When the spring launches the toy into the air, the temperature of the air increases. Explain why the child’s toy on its own is... 06.4 · 1 mark Pressure-driven wheel speed The changes in pressure in the air chamber cause the wheel to turn. Suggest one way to increase the speed at which the wheel turns.
