What is Universal Gravitation?

Back

Universal Gravitation is a fundamental force of nature that describes the attraction between two masses. It states that every point mass attracts every other point mass in the universe 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.

What is the formula for calculating gravitational force?

Back

The formula for gravitational force (F) is given by F = G * (m1 * m2) / r^2, where G is the gravitational constant (6.674 × 10^-11 N(m/kg)^2), m1 and m2 are the masses of the two objects, and r is the distance between their centers.

How does distance affect gravitational force?

Back

The gravitational force decreases as the distance between two masses increases. Specifically, it is inversely proportional to the square of the distance between the centers of the two masses.

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses of the two objects; as either mass increases, the gravitational force increases.
