Newton's Law of Gravitation | Gravitation | Class 11th | NEET | JEE | CBSE | ICSE
Newton's Law of Gravitation states that every point mass attracts every other point mass by a force acting along the line intersecting both points. The force is proportional to the product of their masses and inversely proportional to the square of the distance between them.
Mathematically, this is expressed as:
F = G * (m1 * m2) / r^2
Where:
- F is the gravitational force between the two objects
- G is the gravitational constant (6.67408e-11 N m^2 kg^-2)
- m1 and m2 are the masses of the two objects
- r is the distance between the centers of the two objects
This law explains:
- Why objects fall towards the ground
- Why planets orbit around stars
- Why galaxies move in the universe
- Why tides occur
Newton's Law of Gravitation is a fundamental concept in physics and has far-reaching implications for our understanding of the universe.
Some key points to note:
- Gravity is a universal force that affects everything with mass
- Gravity is a two-way force (both objects attract each other)
- Gravity is a long-range force (it can act over vast distances)
- Gravity is a weak force compared to other fundamental forces like electromagnetism and the strong and weak nuclear forces.
