Physics: Astrophysics: Units
Gbogbo ọrọ náà
The astrophysics section shares its units with forces and motion because orbital calculations use the same mechanics. Speed, distance, time, mass, force and gravitational field strength all carry the same SI units you have already met.
This reference lists the seven units for the astrophysics section and highlights the enormous scales involved when applying them to planets, stars and galaxies.
Ebumnobi
- Use the following units: kilogram (kg), metre (m), metre/second (m/s), metre/second2 (m/s2), newton (N), second (s), newton/kilogram (N/kg)
