What happens to the gravitational force between two masses if the distance between them is increased?

Back

The gravitational force decreases.

Front

How is the radius (r) defined in the context of gravitational force?

Back

The radius is measured from the center of one mass to the center of the other mass.

Back

The gravitational force increases.

State Newton's Law of Universal Gravitation.

Back

The gravitational force between two masses 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

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.
