REVISION NOTES
8.1.1 Use the following units: kilogram (kg), metre (m), metre/second (m/s), metre/second2 (m/s2), newton (N), second (s), newton/kilogram (N/kg)
Mass – kilograms (kg)
Distance – metres (m)
Velocity – metres per second (m/s)
Acceleration – metres per second squared (m/s2)
Force – newtons (N)
Time – seconds (s)
Gravitational field strength – newtons per kilogram (N/kg)
8.1.2 Know that:
8.1.3 Understand why gravitational field strength, g, varies and know that it is different on other planets and the Moon from that on the Earth
8.1.4 Explain that gravitational force:
8.1.5 Describe the differences in the orbits of comets, moons and planets
8.1.6 Use the relationship between orbital speed, orbital radius and time period:
