Circular motion written questions
Solve H1 Physics circular-motion, gravitational-force and satellite questions, then check calculations with worked solutions.
Learning goals
- Express angular displacement in radians and use s = rθ.
- Relate angular velocity, period, frequency and tangential speed using v = rω.
- Explain and apply centripetal acceleration and resultant-force relationships.
- Apply Newton's law of gravitation to point and spherical masses.
- Derive and apply gravitational field strength, including the near-surface model.
- Analyse circular gravitational orbits and geostationary satellite conditions.
