Gravitational fields written questions
Practise H2 Physics gravitational fields, potentials, escape speeds and satellite orbits, then check calculations and explanations with marking guidance.
Learning goals
- Apply Newton's law of gravitation to point and spherical masses.
- Derive and apply gravitational field strength, including the near-surface model.
- Derive the gravitational field strength due to a point mass from Newton's law of gravitation and the definition of field strength.
- Relate gravitational potential, potential energy and field gradient.
- Analyse escape speed using conservation of energy.
- Analyse circular gravitational orbits and geostationary satellite conditions.
