Law of Universal Gravitation

Front

What is the Law of Universal Gravitation?

Back

The Law of Universal Gravitation 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.

Front

What is the formula for 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 of the objects, and r is the distance between the centers of the two masses.

Front

What does the gravitational constant (G) represent?

Back

The gravitational constant (G) is a proportionality factor used in the equation of the Law of Universal Gravitation, which quantifies the strength of the gravitational force between two masses.

Front

What is the value of the gravitational constant (G)?

Back

6.67 x 10^-11 Nm^2/kg^2.

Front

How does mass affect gravitational force?

Back

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

Front

How does distance affect gravitational force?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of two masses; as distance increases, the gravitational force decreases.

Front

What is the inverse-square law in relation to gravity?

Back

The inverse-square law states that the gravitational force between two objects decreases with the square of the distance between them.

Front

If the distance between two objects is doubled, how does the gravitational force change?

Back

If the distance is doubled, the gravitational force becomes one-fourth of its original value.

Front

What is the relationship between force and mass in Newton’s Law of Universal Gravitation?

Back

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

Front

Calculate the gravitational force between two 4500 kg masses that are 0.03 meters apart.

Back

1.5 N.
