Definition
Gravity is a fundamental force of nature that attracts any two objects with mass or energy. On Earth, gravity is what keeps us grounded and affects the weight of everything.
Why it matters (in Poovi’s context)
Gravity is a significant limiting factor for the size of land animals, as their skeletons and muscles must support their entire body weight against this pull. In water, buoyancy mitigates this effect.
Key properties or components

- Acts between masses
- Weakest fundamental force but long-range
- Determines weight
