Understanding Newton's Law of Gravitation

What does Newton's law of universal gravitation state about the force between two objects?

• It is proportional to the product of their masses and inversely proportional to the square of the distance between them.

• It is independent of their masses.

• It is inversely proportional to the product of their masses.

• It is directly proportional to the distance between them.

Which of the following is the correct formula for calculating gravitational force?

• F = G * (m1 + m2) / d^2

• F = G * (m1 * m2) / d^2

• F = G * (m1 * m2) * d^2

• F = G / (m1 * m2 * d^2)

What is the value of the universal gravitational constant, G?

• 6.67 x 10^-11 N m^2/kg^2

• 9.81 m/s^2

• 3.00 x 10^8 m/s

• 1.67 x 10^-27 kg

In the context of gravitational force calculations, why is it important to use the center-to-center distance between two objects?

• Because it is easier to measure.

• Because the force depends on the distance between the centers, not the surfaces.

• Because it is always a constant value.

• Because it simplifies the calculation.

In the example of the satellite orbiting Earth, what is the approximate gravitational force acting on the satellite?

• 4221 newtons

• 3000 newtons

• 6000 newtons

• 5000 newtons
