F g is the gravitational force between m 1 and m 2 , G is the gravitational constant equal to 6.67 × 10 − 11 m 3 kg ⋅ s 2 , and. m 1 and m 2 are masses. The force is directly proportional to the product of the masses. It is also inversely proportional to the square of the distance between the centers of mass.
Sep 1, 2023 · To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object's mass by 9.8 and you'll get its force of gravity!

Newton's law of universal gravitation can be written as a vector equation to account for the direction of the gravitational force as well as its magnitude. In this formula, quantities in bold represent vectors.
G is the universal gravitational constant. It's the constant in the equation F = GMm/r^2. It's value is 6.67E-11 N*m^2/kg^2. Note the units. g is the acceleration due to gravity, which on the surface of the earth is 9.8 m/s^2. See how these units are nothing like the other ones?
In symbols, the magnitude of the attractive force F is equal to G (the gravitational constant, a number the size of which depends on the system of units used and which is a universal constant) multiplied by the product of the masses (m 1 and m 2) and divided by the square of the distance R: F = G(m 1 m 2)/R 2.

F is often the weight of an object on the surface of a large object with mass M, which is usually known. The mass of the smaller object, m, is often known, and G is a universal constant with the same value anywhere in the universe. This equation can be used to solve problems involving an object on or orbiting Earth or other massive celestial ...
Mar 12, 2024 · For two bodies having masses m m and M M with a distance r r between their centers of mass, the equation for Newton’s universal law of gravitation is. F = GmM r2, F = G m M r 2, where F F is the magnitude of the gravitational force and G G is a proportionality factor called the gravitational constant .
