Questions and Answers

What is the formula to calculate gravitational force between two objects?

F = (m * v^2) / r
F = (G * m1 * m2) / r^2 (correct)
F = G * (m1 + m2) / r
F = m * g

What did Isaac Newton's law of universal gravitation state?

Every particle in the universe attracts every other particle 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 (correct)
Gravitational force is directly proportional to the distance between two objects
Gravitational force depends only on the mass of the objects
Gravitational force is inversely proportional to the product of their masses

What is the SI unit of gravitational force?

Joule
Newton (correct)
Watt
Kilogram

Newton's Law of Universal Gravitation

Every particle in the universe attracts every other particle 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.

Gravitational Force Formula

The force of attraction between two objects is calculated by: F = (G * m1 * m2) / r^2 where: F = Gravitational Force, G = Gravitational Constant, m1 = Mass of object 1, m2 = Mass of object 2, r = Distance between the centers of the objects
