CIE iGCSE Co-Ordinated Science P1.5.1 Effects of forces Exam Style Questions Paper 3
Question
(a) Fig. 6.1 shows two horizontal forces acting on a truck as it moves forwards along a flat, level road.
(i) Calculate the magnitude of the resultant horizontal force on the truck.
Draw an arrow on the diagram to show the direction of the resultant force.
magnitude = …………………………………………….. N
(ii) Describe the motion of the truck as the resultant force is applied.
…………………………………………………………………………………………………………………….
(b) The truck has two identical headlamps.
The lamps are connected in parallel across a 12V battery. One switch turns on both lamps. A fuse protects the circuit.
(i) Fig. 6.2 shows an incomplete circuit diagram for this circuit
Fig. 6.2
Complete Fig. 6.2 using standard electrical symbols.
(ii) State one advantage of connecting the lamps in parallel.
………………………………………………………………………………………………………………………….
………………………………………………………………………………………………………………………….
(iii) Complete the sentences about the fuse.
The purpose of a fuse is to ………………………………………………… the circuit. A large
……………………………….. in the circuit causes the fuse to get hot and melt, breaking the circuit.
