🔬 Concepts Covered:
✔ Acceleration due to gravity (g)
✔ Variation of g with latitude
✔ Effect of Earth’s rotation
✔ Centrifugal force at equator
✔ Why g is maximum at poles
✔ Why g is minimum at equator
📚 Concept Explanation:
• At the equator, Earth’s rotation produces centrifugal force
• This reduces effective gravity
• Hence g is slightly less at equator
• At the poles, centrifugal force is zero
• So gravity is maximum
Since time of fall depends on gravity:
t = √(2h / g)
Greater g → less time
Smaller g → more time
Therefore:
⛔ Time taken is NOT same.
