Mathematically, the force of gravity in Newtons (or equivalently, kg m/s2) between any two objects of mass M1and M2separated by r meters is expressed as: Fgrav=GM1M2r2 where the universal **gravitation constant G** = 6.67 × 10-11N m2/kg2...

To convert a mass in kg to a force in Newtons multiply by 9.8 m/s2Another example:Example: a 100kg steel beam sits evenly on two supports. How much force is on each support? The beam exerts a downwards force due to gravity: F = mg F = 100 kg × 9.8 m/s2 = 980 N As it ...
Let’s say this force is about 800 Newtons when you’re standing at sea level. If you traveled to the Dead Sea, the force would increase by a tiny fraction of a percent. And if you climbed to the top of M...
While the theory of Newtonian potentials has various aspects, it is best introduced as a body of results on the properties of forces which are characterized by Newtons Law of Universal Gravitation.Every particle of matter in the universe attracts every other particle, with a force whose direction...
The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately 6.67430(15) x 10-11 Newtons (m2/kg2). Gravity and Everyday Objects The gravitational attraction between everyday objects...
This results in the equation of a parabola, where the constant k = 2vh2/g:x2 = ky When curvature is a factorFor greater distances, the curvature of the Earth becomes a factor and complicates the equation.When the ground is considered flat, the force of gravity is perpendicular to the ...
NB: kg are actually units of mass (the units of force are N = Newtons, where the force on a 1 kg weight at sea level = 9.8 N). The weight (or force) exerted by a given mass depends on how close it is to the earth’s gravity, so here sea level is assumed. Notes Einstein sa...
Newton quantified the attractive force between two masses to be: where: Fg is the gravitational force between two masses in newtons (N) G is the universal gravitational constant, which is 6.67 x 10-11 (N⋅m2 / kg2) m1 and m2 are masses 1 and 2, respectively r is the distanc...
. It is a property of the object that reflects its quantity of inertia. Weight, on the other hand, is the force due to gravity exerted on a massive body, and it is measured in Newtons.Example: How to Find the Force of Gravity? Lesson Summary Register to view this lesson Are you a ...
