Explain how the concept of escape speed relates to the event horizon of a black hole.
Model answer
What a good answer should say
- The escape speed at the event horizon of a black hole is equal to the speed of light.
- This means that any object reaching this boundary cannot escape the black hole's gravitational pull, as it would require a speed greater than light to do so.
Explanation
Why this works
This answer effectively links escape speed to the event horizon, demonstrating an understanding of the physical principles governing black holes. The question assesses the student's ability to articulate the relationship between these two concepts.
