Exam-style question
Try this first
A satellite is in a circular orbit around a planet. Explain how the gravitational force acts as the centripetal force required for the satellite's circular motion.
Model answer
What a good answer should say
- The gravitational force between the planet and the satellite provides the necessary centripetal force to keep the satellite in its circular orbit.
- This force acts towards the center of the planet, ensuring that the satellite continuously changes direction, maintaining its orbit.
Explanation
Why this works
This question tests the understanding of the relationship between gravitational force and centripetal force in circular motion. A strong answer clearly links the two concepts and explains the role of gravitational force in maintaining the satellite's orbit.
