Question

Which one of the following does not accurately describe the universal gravitational law? A. Gravitational force is proportional to the square of the distance between the centers of both bodies. B. The object with the smaller mass does most of the moving because the object with the larger mass has too much inertia to move any noticeable amount. C. Gravitational force is proportional to the product of the two masses. D. Every object in the universe that has mass attracts every other object in the universe that has mass.

Answer 1

A. Gravitational force is proportional to the square of the distance between the centers of both bodies.

FALSE:

Gravitational force is inversely proportional to the square of the distance between the centers of both bodies.

Which you can see from the formula: F = G * [m*M] /(d^2)

As you see in the equation, d^2 is in the denominator so the bigger d^2 (the square of the distance between the centers) of the objects the smaller the gravitational force.

B. The object with the smaller mass does most of the moving because the object with the larger mass has too much inertia to move any noticeable amount.

TRUE:

F = mass * acceleration => acceleration = F / mass => the larger the mass the smaller the acceleration.

C. Gravitational force is proportional to the product of the two masses.

TRUE:

F = G [m*M] / (d^2)

The product of the two masses, m*M, is in the numerator, so F is proportional to this product.

D. Every object in the universe that has mass attracts every other object in the universe that has mass.

TRUE: that is a Universal Law discovered by Sir Isaac Newton.

Answer 2
