The Earth’s gravitational force is the force of attraction that the Earth exerts on objects near its surface due to its mass.
Gravity is a fundamental force of nature that governs the motion of celestial bodies, including planets, moons, and satellites.
It is what keeps everything anchored to the Earth and gives weight to objects.
The concept of gravitational force is described by Sir Isaac Newton’s law of universal gravitation, which states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Mathematically, the equation for gravitational force (F) between two objects (m1 and m2) separated by a distance (r) is given by:
F = G * (m1 * m2) / r^2
where:
- F is the gravitational force between the objects (measured in Newtons, N).
- G is the gravitational constant, approximately 6.674 × 10^-11 N m^2/kg^2.
- m1 and m2 are the masses of the two objects (measured in kilograms, kg).
- r is the distance between the centers of the two objects (measured in meters, m).
