* As distance increases, the force of gravity decreases.
* As distance decreases, the force of gravity increases.
This relationship is described by Newton's Law of Universal Gravitation:
F = G * (m1 * m2) / r²
Where:
* F is the force of gravity
* G is the gravitational constant (approximately 6.674 × 10⁻¹¹ N⋅m²/kg²)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
Key Points:
* The force of gravity decreases rapidly with increasing distance. This is because the force is inversely proportional to the square of the distance.
* Even at very large distances, there is still a gravitational force. It just becomes extremely weak.
* This relationship explains why we are held to the Earth's surface, but not pulled towards the Moon. The Earth is much closer and has a much larger mass than the Moon.
Example:
If you double the distance between two objects, the force of gravity between them will decrease to one-fourth of its original value. This is because you are squaring the distance in the denominator of the equation.
In simpler terms, imagine you have a magnet and a piece of metal. The closer you bring them together, the stronger the magnetic force pulls the metal. The further apart they are, the weaker the force. Gravity works in a similar way, but with mass instead of magnetic charge.
