Sonali and Ragini set off cycling on a windy day. The wind pushed against them, rough roads slowed them, and coming downhill they sped up without pedalling at all. "Something is pulling us downhill — what could it be?" Let's follow their ride and meet the forces hiding in it.
- The wind pushed against them, so they had to pedal harder.
- Rough parts of the road were harder to ride than smooth parts.
- They turned the handle to change direction near the sheep.
- Going downhill, something pulled them down fast without pedalling.
- The wind, the rough road, and the downhill pull are all forces.
- Each one is a push or a pull acting on the cycle.
- This chapter names and explains all these forces.
