🎯 Exam Focus — Orbits
Examined in Edexcel 1PH0/1 (Paper 1). Context-based questions use real satellite data and mission scenarios. Calculation focus: orbital speeds (v = 2πr / T) and the relationship between orbital radius and period. "Suggest" questions appear for novel orbital scenarios.
What examiners love to ask:
- Explain why gravity provides centripetal force for orbits
- Compare circular and elliptical orbits (speed and force variation)
- Calculate orbital speed from radius and period
- Describe geostationary vs low Earth orbit — uses and differences
- Explain why closer orbits require faster speeds
