eli5: What is an inverse square force and how is gravity an inverse square force?
In: Physics
An inverse square force is a force whose strength decreases with the square of its distance.
Say you are touching a magnet and you can feel it’s force. Now, if you move 2 metres away from the magnet, you will feel that it’s force is 4 times less (as 2² = 4).
Gravity is an inverse square force as it follows the same rule.
Why does Gravity follow this rule? No one knows for sure.
