What does Newton's gravitational law state?

• Newton's gravitational law states that objects with larger masses fall faster than objects with smaller masses.

• Every particle attracts every other particle 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 them.

• Gravity only affects objects with large masses.

• Every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the distance between them.

What is the SI unit of the universal gravitational constant?

• N m^2/kg^2

• kg^2/N m^2

• N m^2

• N m^2/kg

What is the formula for calculating the gravitational force between two objects?

• F = (G * m1 * m2) / r^3

• F = (G * m1 * m2) / r^2

• F = (G * m1 * m2) / r

• F = (G * m1 * m2) * r^2
