Worked Example
Formula warm-up 3
For Class 11 Physics, explain or solve a newton's universal law of gravitation question from the chapter "Gravitation". Focus on formula warm-up and show the working clearly.
Step-by-step solution path
- Read the topic idea: Newton's Universal Law of Gravitation.
- Recall the core explanation from the chapter: Newton's law of gravitation, Kepler's laws, orbital velocity, escape velocity and satellites.
- Use the related formula "g at height h" as the main tool while solving.
- Write the reasoning in simple school-level language before the final answer.
Final learning answer
This example is centred on Newton's Universal Law of Gravitation. A strong solution should identify the correct data, apply g at height h, and explain each transition instead of jumping directly to the answer.

g at height h
g_h = g(R/(R+h))² ≈ g(1-2h/R) for h<<R
