Here's the breakdown:
* Newton's Law of Universal Gravitation: This law describes the force of gravity between any two objects with mass.
* Formula: The force of gravity (F) is directly proportional to the product of the masses (m1 and m2) and inversely proportional to the square of the distance (r) between their centers:
F = G * (m1 * m2) / r²
Where:
* G is the gravitational constant, approximately 6.674 x 10⁻¹¹ N⋅m²/kg². It's a fundamental constant in the universe.
Key points to remember:
* Mass: The more massive the objects, the stronger the gravitational attraction.
* Distance: The farther apart the objects are, the weaker the gravitational attraction.
* Inverse square law: The force of gravity decreases rapidly as the distance between the objects increases.
Examples:
* The Earth and the Moon: The Earth's gravity pulls on the Moon, keeping it in orbit.
* You and the Earth: The Earth's gravity pulls on you, keeping your feet firmly planted on the ground.
* Stars in a galaxy: Gravity holds stars together in galaxies.
