Questions and Answers

What is the expression for the Universal Law of Gravitation?

$F = G \cdot \frac{M \cdot m}{d}$

$F = \frac{G \cdot M \cdot m}{d^2}$ (correct)

$F = \frac{G \cdot M \cdot m}{d}$

$F = G \cdot \frac{M \cdot m}{d^2}$

What is the force of attraction between two objects according to the Universal Law of Gravitation?

Directly proportional to the sum of their masses and inversely proportional to the cube of the distance between them

Inversely proportional to the product of their masses and directly proportional to the cube of the distance between them

Directly proportional to the product of their masses and inversely proportional to the square of the distance between them (correct)

Directly proportional to the square of the distance between them and inversely proportional to the product of their masses

Study Notes

Universal Law of Gravitation

The expression for the Universal Law of Gravitation is: F = G * (m1 * m2) / r^2, where F is the force of attraction, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.

Force of Attraction

The force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Distance and Gravitation

The Universal Law of Gravitation states that the force of attraction between two objects decreases with an increase in the distance between them.

Alternative Names

The Law of Gravitation is also known as the Law of Universal Gravitation or Newton's Law of Gravitation.

Doubling Mass and Halving Distance

If the masses of two objects are doubled and the distance between them is halved, the force of attraction between them will increase by a factor of 8.
