A page about weight as a property of matter.
The Main Idea
In physics, weight describes the Gravitational Force upon a mass, usually relative to Earth or a planet. Depending on the source, weight may be defined as a scalar - the magnitude of the gravitational force on an object - or a vector equal to gravitational force. An object's weight is commonly confused with mass, but instead it is a force that depends on another body of matter, while mass is an intrinsic property of matter.
A Mathematical Model
A mass m's weight near the surface of the Earth is represented by [math]\displaystyle{ {\vec{W} = \vec{F}_{g} = {mg}} }[/math] where g is the gravitation acceleration of Earth, -9.8 meters per second squared.
[math]\displaystyle{ {\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net} }[/math] where p is the momentum of the system and F is the net force from the surroundings.
A Computational Model
A simple segment of code that calculates the both scalar and vector weight (gravitational force) exerted upon a ball.
