The force of gravity is a fundamental interaction that attracts two objects with mass. It is described by Newton’s Law of Universal Gravitation:
[ F = G \frac{m_1 m_2}{r^2} ]
Where:
(F) = gravitational force
(G) = gravitational constant ((6.674 \times 10^{-11} , \text{Nm}^2/\text{kg}^2))
(m_1, m_2) = masses of the objects
(r) = distance between their centers
Key Points:
Universal Pull: Acts between all masses, from apples falling (Earth’s gravity) to planets orbiting the Sun.
Weak but Infinite Range: Gravity is the weakest fundamental force but operates across cosmic distances.
Earth’s Gravity: Accelerates objects at (9.8 , \text{m/s}^2) (denoted as (g)), calculated as (F = mg).
Einstein’s View: General Relativity redefines gravity as the curvature of spacetime by mass/energy.
Examples:
Your weight is the gravitational force Earth exerts on you.
The Moon’s gravity causes ocean tides.
Gravity shapes the universe, governing motion from falling leaves to galaxy formation. Though mathematically simple, its effects are profound, making life and cosmic structure possible.
