GCSE AQA Physics Forces & their Interactions: Figure 3 shows a cyclist on a bi

Question

Figure 3 shows a cyclist on a bicycle.

The cyclist is moving at a constant velocity.

Arrows A and B represent the horizontal forces acting on the bicycle and cyclist.

---

**02.1** What is force A? 
Tick (✓) one box.
- Air resistance
- Friction
- Tension
- Upthrust

---

**02.2** What is force B? 
Tick (✓) one box.
- Air resistance
- Magnetic
- Tension
- Upthrust

---

**02.3** What is the relationship between force A and force B when the cyclist travels at a constant velocity? 
Tick (✓) one box.
- A = B 
- A > B 
- A < B

---

**02.4** The cyclist applies a force of 150 N to one of the bicycle pedals.

Figure 4 shows the distance between the force applied and the pivot.

Calculate the moment about the pivot caused by the force applied to the pedal in Figure 4.
Use the equation: 
moment of a force = force × distance

**02.5** Figure 5 shows how the pedal is connected to the back wheel of the bicycle.

Complete the sentence.
Choose the answer from the box.
- axle
- chain
- cog

The force from the cyclist pushing down on the pedal is transmitted to the back wheel by the __________.

**02.9** The cyclist travels from home to school.

Figure 7 shows the route the cyclist followed.

Draw an arrow on Figure 7 to show the displacement of the cyclist.
