The formula for gravitational acceleration at height h above the Earth's surface is
- gₕ = g × (R + h)² / R²
- gₕ = g × (R / (R + h))²
- gₕ = g × (R - h)² / R²
- gₕ = g × (R / h)²
Explanation
Gravitational acceleration at a height h above Earth's surface is less than at the surface.
- Formula: gₕ = g × (R / (R + h))²
- As h increases, gₕ decreases.
- This is due to the inverse square law of gravity: force (and thus acceleration) weakens with the square of the distance from the center of the Earth.
- At very high altitudes (like satellites), gravity is still present but weaker.
